First Thoughts on the Eclipse IDE? 266

Posted by Cliff from the looks-like-it-has-some-promise dept.
OpenSourcerer asks: "Has anyone used the opensource IDE Eclipse. Initial impression is that of a slightly slow but very modular and configurable IDE. Anyone else has any experience using this?" I must say that the idea is novel enough, instead of building an environment around a specific language/compiler, you build a framework and have plugins support the specific features that you want. Java development tools have already been released and it looks like the C/C++ project is just getting under way. For those of you who have given the Eclipse project a quick look, what do you think?

      What sort of "mission critical" things are you talking about when it comes to IDE's? I mean, if it doesn't work, you just take out the offending plugin and do it without it. It's not like an IDE has to be a high-availability server-type thing. Obviously, it can't always be breaking and crashing or productivity suffers, but it's not like one crash of a properly backed-up project is going to end things.

    What's so novel about this? emacs has been like this for years!
    • But I'd hate to run an entire system through emacs.
    • The first project that I can think that did this was turbovision, the environment used for Turbo C, Turbo Pascal, etc, and which is now used in exactly such an environment.

      In fact, most of the modern professional GUIs are used for multiple languages. I have a theory as to why: the constructs of a language are basically the same, meaning that if a company wishes to create IDEs for multiple languages, then the best way would simply be to make a parser front-end that converts everything to data structures. It is therefore in their best interest to make IDEs modular.

      But...I can think of a very good reason for keeping a GUIs language-independant. For languages that have it, introspection has allowed IDEs to detect structures far better than the traditional IDE - case in point is Borland's JBuilder, which can be used to modify a user interface using RAD which was hand-created (most IDEs can't do that). However, this requires that the RAD be written in the language - making it NOT language-independant.

      My conclusion is that having an all-in-one IDE is kind of like having an all-in-one printer/scanner/fax. Sure, all of the features work, but none of them work really well.

      Of course, I suppose we could have a GUI for C/C++, Fortran, Cobol, and Assembly, since all of those are strictly compiled (I know there are other compiled languages, but those are the ones that lots of people use).

        Windowing-system specific features aren't Java -- they are implemented natively through a windowing abstraction called SWT (Standard Widget Toolkit) rather than using Sun's Swing toolkit. That's why the system looks different on different platforms, since the appearance of widgets is determined by the underlying GUI implementation.

          The platform-specific features most certainly are in Java. Read the SWT white paper [eclipse.org]. Native interfacing is used only to get at the raw APIs.

          Indeed, IMO SWT is the most interesting aspect of the Eclipse project!

    • It runs on linux, but looks like ass, and is slow. It runs and looks *great* on win2k, though.

      Totally agreed. If only it runs as well on Linux as on W2K, I'll be using it everyday. And for god-sake, why Motif (when was Eclipse first developed)?

      And, how about customizable key bindings? I want my Emacs keybindings in Eclipse too.
      • I haven't tried the Eclipse builds, rather only the IBM branded (and modified) version called WebSphere Studio Application Developer. The linux builds for this were only in alpha (they're now in beta) so I can't say they're finished, but the speed wasn't horrible and I can only assume that by the time WSAD (and Eclipse) are in their final states, there will be very little difference in performance between W2K and Linux platforms.

        As for Motif? Probably to maximize platform cross-compatibility. Eclipse was first publicly announced/released (by IBM) late last year.

        Finally the customized key bindings are probably a safe bet. Emacs key bindings are present in VisualAge and oft used so I can only assume that they'll be available immediately in WSAD (but I haven't checked in the builds I've run). If not, they should be addable with relative ease.

    The problems that come up will be "sins of omission". In order to avoid breaking a generalized interface, plugin makers may not create an interface the way that makes the most sense for a certain language.

    Eg: has anyone used Visual Basic? The interface is built around what the language is good at (and the interface is a main reason for its popularity). While the same functionality could have come via a plugin, likely it wouldn't have. Instead, a tool like the form editor would be bundled with the other resources, rather than front and center in coding. This makes coding other types of projects awkward, but they aren't VB's strengths anyway...

    In short, I think there are advantages to building a UI solely around a specific language.

      Yes, I have used VB extensively, and I disagree with you. When you use VB for a large project you spend most of the time in the code editor, not the form editor. In fact, many VB style guides recommend keeping the quantity of code in the form modules to a bare minimum (ie: just method, procedure or function calls in the event handlers). There's no reason why the same Visual Basic IDE interface couldn't have been developed from a generalized interface.

      The reason that the VB IDE is so good is because the developers spent more time on improving the environment than on making the internals of the compiler work better. I haven't used it since VB5, but even then, you could compile the same code 2 times in a row and it would yield two different executable sizes.

      I've never used an IDE that I liked aside from VB. The jump to function definition, code completion, and popup argument list features worked better than any other tool I've used. For Java (which is what I use for most programming these days) I like Vim + ctags + ant which is also pretty nice.

      My dream IDE (which Eclipse may be able to become) would integrate a database design / er modeling tool, a UML modeling tool, a code editor, build system, database management tool, and version control. You should be able to put the cursor on a text string that's a stored procedure call, and press a keystroke that would bring up a Database window with the text of the stored procedure which you could modify and then replace on the DB server. Then another keystroke would jump you back to the client code where you call the stored procedure.

      Good luck to those guys.

      • My point is not that you couldn't have arrived at a VB style IDE from a generalized one, but that you probably wouldn't.

        I agree that dumping code in the .frm file isn't a good idea - but the intuitiveness of doing so (double click on a button to add some code) appeals to a lot of programmers - it's just the sort of feature that plays to VB's strengths.

        But it's not the sort of feature that would likely be in a plugin for a generic IDE. Why corrupt a perfectly good form editor by having it spew code into some linked module? The very idea of having code in a .frm would just not fit in with the paradigm of a good generic language tool.

        Anywho, doesn't much matter. And I too hope that they come up with a good project.

        This makes me giggle. Emacs is quite the cross platform app - it runs on just about anything that will run a display and the interesting bits of it are done in lisp - every bit as machine independent as java.

      • > Eclipse is designed for a much broader audience

        So, like Emacs, it is also designed to be used for non-programmers? Emacs is not just designed to be an IDE, it is designed for all tasks that can somehow be conceived to be related to text editing. Aiding programmers is just one aspect.

        You mean it is written in a propritary, unportable language, using propritary, unportable hooks, which Sun marketing have somehow managed to convince a generation of inexperienced programmers is a synonym of "portability"?

        There is only one usful definition of portable, and that is ported. I bet Emacs runs on platforms that does not and will never run Java applications, certainly not ones relying on Windows/Motif/Gtk+ calls. Emacs can ustilize thes libraries, but doesn't rely on them.

        I'm sure Eclipse is useul, it provides an alternative to people who dislike the Emacs UI, and probably even have unique features. But broadness in either application range or platform range are not among these.

    I did a review of a few of the IDEs out there ,primarily for their java stuff. Based on my short try out, Eclipse wasn't wuite there for the Java stuff, but that would have been the plug in. I ended up with IDEA, and we'll probably have a few people here singing it's praises.

    I think that the IDE still really needs to understanf the language to be effective, but maybe the plug-ins will solve that.

    The cool things in IDEA, and I would love to see in Eclipse, is the refactorings, the ability to have multiple configurations for running and debugging in a single project (nice for unit tests), and the ability to run one program while debugging another, great for client-server type programming (If you view Servlets as the client, and EJBs as the server, but would work for other stuff as well.)

It is a bit slow, but as Java apps go its not bad at all. Compared to JBuilder or Forte its veritable speed deamon (althow start up is rather slow).

  • The most transparent (as in instantly responsive, and requiring no mental effort expended on performing rote tasks) IDE is two text editor (I favor emacs, but that's another rant) windows side by side on a 21 inch monitor, and half-a dozen xterms with shell prompts. Set up your repeated commands each in a shell, such that a trivial two-keystroke command will execute them. Important: set your mouse focus to be location based, not requiring a click to activate a window.

    Thus, the only time your hands need to leave the keyboard is to make a vague mouse "gesture", moving to a general area of the screen to place the cursor in an xterm. None of this hunting through pulldown menus for the cryptic command that does desired variation of "Make (force | clean | all | libraries | autogen)".

    A side benefit is that you're using gnu-make to do your builds (unless you're an idiot), so there's no bullshit build dependencies on somebody's favorite IDE.
    • Dude! That's exactly how my IDE works! Except make that several xterms across several desktops under X.

      • I should also mention that when I am writing documentation or some other bit of doggerel, I use the exact same set up, emacs, xterms & make (building with LaTeX underneath instead of gcc).


        I have gone without using a word processor on Linux for well over a year now. :-)

    • Except for the fact that make is inherently evil. If you meant ant for Java related development, then I'd mostly agree with you. The upside to Eclipse is that it has ant integration, meaning you can develop both from within Eclipse and a command-line framework.

      • Except for the fact that make is inherently evil. If you meant ant for Java related development, then I'd mostly agree with you.

        Getting off-topic here, but what's so evil about gnu-make w/ java? I've been using it for a couple years with java, including EJB-based projects. Ant kind of looks like a solution in search of a problem.
        • If you write a typical Makefile for Java the way you do it for C/C++ (with rules for .java.class, dependencies etc.) make takes much too long on any largish project.

          This is because it invokes javac (or whatever compiler you're using) once for every changed file, and javac is slow as hell to startup (create a new VM, load the compiler classes and so on).

          Ant only invokes javac once, reusing the same VM, thus saving you tons of time.

          • For my current Java project, my IDE consists of NEdit plus a couple of supporting perl scripts which handle compiling, .war-ing and rebuilding my project, along with restarting tomcat (though Tomcat 4.0 doesn't need to be restarted when your classes change i hear)

            my 'build.pl' invokes javac once for all the files that need compilation - it checks my source folders for changed timestamps and recompiles all the changed files with one invocation of 'javac'.

            NEdit is a hell of a lot faster than JBuilder's editor, stdout isn't as slow as molasses like it is with both netbeans and JBuilder (haven't tried Eclipse yet) and i don't miss the 'IDE' features at all, though during initial development the auto-completion and GUI interface builder might come in handy.

            My litte psuedo-IDE doesn't have all the features of JBuilder,Netbeans or Eclipse but its only about 100-200 lines of perl altogether and gets the job done perfectly.

            My next project will be developed using Project Builder on OS X, which while not super-fast for java development , is complete, with a decent editor (though it lacks auto-complete, unless i have missed the menu option to turn this on) and stable with a very nice GUI interface builder.

    They advertise that this program has the ability (given proper plugins) to read any content type, modify it, and keep everything in a tidy package to present a uniform interface to a user. You could seriously modify their product description and replace "plug-in" with "application" and you could describe pretty much any OS in existence.

Way better than unlimited undos, which a lot of editors have. Kind of a mini-source control available for those "oh shit" moments of deletion. You can set how long previous changes are saved. Neato.

      I'll give you an amen on that.

      I paid $400 for my copy and it was entirely worth it just for the refactorings. Heck, the cross-project rename was worth the money you can click on a method or variable and safely rename every use of it, while leaving other symbols with identical names untouched.

    I was really positive about the technology it's built on from reading about it. Unfortunately when I installed it on my RedHat 7.2 box I got a rude shock... Even pure Java editors like Jext and Forte were blindingly fast compared to Eclipse. The box is a dual PIII 450 with 512 megs of ram, and Eclipse took more than a minute to open, then I could go get a cup of coffee between screen refreshes. I was the only one logged in and I don't run any servers on it, so the box was definately not low on resources.

    I heard similar things from other people trying to use it under Linux and decided to leave it for a while. Have any workarounds been found?
  • Isn't netbeans/forte the same thing, an ide base, with alot of developer plugins floating around it? It's based on a Java core and not a C core, but other than that, is eclipse that same or even more modular..?
  • I liked Eclipse for the most part... It had some of the good features of VisualAge but was less annoying and didn't hide all your code in a repository database.

    However, there's a feature of the Java and/or JDE modes in XEmacs that I've become unable to live without:

    When you hit Tab, it doesn't necessarily insert some fixed number of spaces or tabs. It simply indents the current line properly. You know immediately that you're missing a bracket or a semicolon when you hit Tab and:

    • Nothing happens, or;

How am I supposed to know if it's worth the trouble of compiling it all? How am I supposed to know if I'll like the interface? I just don't get it.

    Some of these open source projects really need to get their rear in gear and start trying to sell their stuff.

    by Johnath ( 85825 ) on Friday January 04, 2002 @05:22PM (#2787886) Homepage

    Heh, I just can't get over the fact that the IDE we've been using internally for the last 6 months is getting so much play on slashdot and in the world-at-large.

    One thing that's important to remember about eclipse is that it is a great deal more than your basic IDE. The pluggability really means that anything you can do in Java (or in principle, any language), you can make eclipse do. My department is focused entirely on using eclipse as an *application platform*. Think big. Yes, you can make it into a C/C++/Scheme/ML IDE, think bigger. Yes, you could definitely write a word processor plugin, and maybe plugin-ize an existing product. Think bigger. There's no reason in principle why you couldn't make a set of plugins that, for instance, made eclipse into something like zope or websphere -- your IDE could let you edit your php/jsp/perl, and then act as your development webserver too, for rapid prototyping. I dunno, I'm just pulling random things out of the air :) The point is, calling it modular might not be... emphatic enough. :)

    As an IDE, it's pretty solid, I definitely encourage java developers to check it out, and as the C/C++ plugins solidify, I expect I'll move to it for my own C/C++ development too, if for no other reason than that I use it at work all the time. :) One thing that is both a blessing and a curse is that it does not (at least, our internal versions do not) come with a repository system a la Visual Age (IBM's older, less extensible Java IDE) -- instead that's up to you - we have teams using basic file system, cvs, cvs over ssh, and CMVC (a defect tracking and team file management tool that I imagine few outside IBM have ever seen. :) A curse in that out-of-the-box, you don't have team-managed repositories working like in VAJ, but a blessing in that you get to set up whatever fool system you like, maybe even keep whatever system you're already using. :)

    Anyhow, just a few thoughts, the previous posts I've seen on eclipse seem to understate its extensibility. It's got the potential to be this decade's emacs - the application that is almost an operating system. :)

    • The lack of a repository is definitely a blessing for no reason other than the fact that no one will be tempted to use it.

      • It's got the potential to be this decade's emacs


      Doesn't emacs still fill this role?

      -yb

    • VisualAge for Java's insistence on doing its team repository its own way is precisely the reason my company didn't buy it.

      One of the most important features for any development platform, be it merely an editor (although you can't call emacs 'merely' an editor!), up through something like Eclipse, NetBeans or JBuilder, is integration with current practices. Especially in cases where people have potentially invested a whole lot of money in the way they do things already.

      As a more off-topic aside... from the IDE evaluation work I've done, to come up with that recommendation, I'd have to say that the key to that level of integration isn't even pluggability, though that's nice. It's just one simple principle: source code should always be plain text. VAJ's primary, number one sin, right there, was getting that wrong. Everything, absolutely everything, works with plain text.

    • I d/led it and thought that it was a great editor. I'd use it instead of Forte except for one thing. I don't like the debugger, or maybe it doesn't like me cause I can make the debugger crash like mad. Forte's debugger works great for me. But damn I like the speed of it. It really shows that it's not Java or the JVM that's slow, it's the crazy AWT/Swing interface to the OS that causes java apps to act so slowly.
    • Yes, plugins are great but what you're touting here has been done long time ago by your competitors: Borland. JBuilder has its api for plugin development called OpenTools. With OpenTools you can make JBuilder do anything. And when I say anything I mean it. Open Tools is basically your own java code called by JBuilder when the user performs an action defined in the OpenTool itself. For example I wrote multiple plugins that add themselves as menu items to the Project menu in JBuilder and run some code parsing and display results in the info pane.
    • Anybody working on a C# plug-in for Eclipse? Could Ximian's work be incorporated in here?
  • I haven't looked at it - but the plugin idea sounds like Forte for Java / aka. Netbeans - no?
  • I'm a full java developer. We ( my java dev team ) tried several java IDEs for a long time. And we sticked to JEdit for performance reasons. It's not an IDE, but it's the best programmer-oriented editor I have worked with to date; All java IDES we tried ( Borland's JBuilder, Oracle's JDeveloper and SUNs netbeans ) were so big and dogslow that we prefer the little and cute JEdit. Recently I began to work with IBM's eclipse, and now I am totally adicted to it. It's fast and confortable to work with ( good debugger and have intellysense-like functionality ). The windows versions feels like it was made by MS, but the linux version it's still slow (but workable) and feels horrible under it's patetic motif skin. I hope the IBM guys write the KDE port soon. If you think that MS were demanded by Sun for trying to make a native extension of java, it's so ironic to see IBM doing the same thing and make everyone happy ;-)

    I find it very userfriendly and some of the features like the plugable JDK's are a god send for testing on multiple vendor JDK's. The ablilty to assosiate source and API documentation with libaries to trace back exceptions or the javadoc info for classes within the editor makes working with new API's a greate deal easier.

    On a comparison note the only other Java IDE i've used was Oracle's JDeveloper which i found a lot harder to get to grips with.

  • " I must say that the idea is novel enough, instead of building an environment around a specific language/compiler, you build a framework and have plugins support the specific features that you want.

    I've been using this one awhile. I used to use Visual Age for Java for Linux but IBM discontinued that after version 3.0, which left me with no way to write JDK 1.2 apps. Eclipse makes me want to forgive them for that. It has some of the best features of VAJ and has some great new features.

    For instance, VAJ was always difficult to use with CVS, but Eclipse support for CVS could not be better. Really outstanding.

    Eclipse does need more memory than VAJ did (I run both on an IBM Aptiva with 64 mb of memory and the difference is notable) but given enough memory it runs fine. For those reporting stability problems remember that Eclipse runs under Java and all Java IDEs under Linux are not equal. IBM's tend to work best but they aren't flawless. The IBM JDK does work better than Sun/Blackdown for running Eclipse so try that and see if you don't like Eclipse better.

    Eclipse so far lacks a GUI design tool but there seem to be several people at IBM and elsewhere working on one, so we should have several to choose from in time.

    I like very much that Eclipse is the base for IBM's commercial offering WebSphere Application Developer (the successor to Visual Age for Java). This means that most plugins written for Windows should also be available on the Linux side and that IBM should be able to offer a Linux version of WSAD without much extra effort (something that probably wasn't true of VAJ.)

    I find Eclipse very useable on its own and it has been a great help to my own free software project.

  • If I'm understanding this correctly, there is a plug-in arbitecture for the IDE to allow it to be customized to anyone's needs.

    Guess what? Metrowerks has been doing this for years. CodeWarrior was modular and allowed the user/developer to extend the IDE in pretty much unlimited ways.
  • My favorite windows text editor Textpad (http://www.textpad.com/) allows modular syntax highlighting, and supports scripting commandline things (compile this using...., send through cvs, etc) into the dropdown menus. It recognizes and can save things 'unix style'.

    Better yet it is freely downloadable ($20 for a few 'advanced features'). One of my required apps with any windows install.
  • NeXT (and now Apple) have Project Builder and Interface Builder, which were language neutral, and PB supports Java, C, C++, Objective-C, and people can make plugins to support various other languages.

    It's the magic of O-O when applied properly. And those tools existed at least as far back as 1989!
  • There are even screen shots there.
    Or am I missing somthing, does Eclipse offer something more?
  • Anyone have a screenshot of this butt-ugly program?

    ;)
  • My company forces me to do my development on Windows so I've been changing editors a lot to figure out what I'd like to use.

    For the previous two months I was using Jbuilder 4 from Borland (the free one) and found it quite limiting. Jbuilder claims to have an emacs keymapping, but it wasn't close enough, and didn't allow me to customize. Plus Jbuilder was fairly slow compared to Eclipse.

    Eclipse has very nice window support, allowing me to position my workspace how I'd like. The remote debugger was very easy to attach to my weblogic instance, and I've found the editor to be acceptable so far. (I haven't tried switching to using Emac's shortcuts yet... ).

    Unfortunately Emac's just isn't integrated enough for me to do Java development. I still use it for my regular editor and quick cleanups though.

    Eclipse brings in some features from VisualAge for Java that I've always loved. First, every single time I hit "Save", it compiles. I get immediate feedback. Second, the scrapbook rules. Being able to try a bit of Java code at any time is great.

    I'm quite happy with the painless CVS integration. Eclipse has the easiest CVS/SSH setup I've ever seen. I'm able to reference multiple CVS repositories from my workspace without even thinking about it.

    The different perspectives take getting used to. I still get lost from time to time. I don't know which one I'm in and I don't know it until I get the "wrong" context menu. It doesn't help that all the perspective icons look alike.

    I've now been using and proselytizing Eclipse for several months. A "quick" view of it, even a couple of days, does no more to reveal its strength and depth than a similar spin of Emacs. Eclipse is rich in detail.

    The technology is very well thought out. What seperates it from things like NetBeans is that plugsins are beyond first-class objects: they are the only type of object.

    Let me explain. Everything in Eclipse is a plugin. Plugins publish (as XML) things called "extension points" that other plugins hook into. All that XML is processed at bootup time, and it allows the basic Eclipse engine to do a lot without loading much Java code. Plugins declare new menu items, tool bars, editors, actions, whatever but no Java code is loaded until the user actively selects on of those new options.

    I'm personally looking forward to writing some plugsin related to by own open source project, Tapestry [sf.net].

    I've also been very impressed by their very open process. They have an open Bugzilla and very quick response times to bugs and issues. Several suggestions I've made have already made it into the project, and they don't know me from Adam. Eclipse is not perfect, but they are very keen on improving the rough edges.

    The interface is very clean and configurable, it really molds to how you, the user, want to run things. All those draggable views and all.

    There's already a C/C++ plugin. I'd love to see a Python plugin (perhaps using Jython?). There's a huge amount of functionality that hasn't been documented yet (do I smell an O'Reilly book?).

    I find it to be about has fast as Netbeans on my work machine (PIII 1ghz, 512MB) and a lot easier and more intuitive to use and configure. The UI is snappier (and prettier), and its loaded with features. It's like Emacs, you keep discoverring new things it does.

    Hey -

    I've been using Eclipse now for a couple of weeks, and have managed to bring an existing Java project consisting of a couple hundred source files into it, and compiling fine.

    Things I Like:

    1> Great code editor. Nice highlighting of matching parens and curly braces. Fairly instantaneous pop-up of attributes and methods when you press the period.

    2> JUnit integration is strong. JUnit is good -it won't solve all your problems, but it's a nice safety net.

    3> CVS Integration. Good source control integration is a must, otherwise I won't use it.

    Things I'm not so keen on:

    1> Seems to be good for Java, but not much else. I know it's still early, but I'd like to see more support for web targetted development.

    2> Since it's supposedly using Ant behind the scenes, where's the XML config, and a GUI editor for said config? That would go a long way toward fixing #1 above.

    Anyhow - with CVS integration, and JUnit, I'm not looking back. NetBeans was OK - but slow as heck, even if it bundles in more functionality. I'm betting Eclipse will gain rapidly.

    Best thing that happened, was it got me looking around for a Java IDE, and discovered that NetBeans had gotten infinitely better since the last time I had looked at it. I've been using it ever since. NetBeans smokes it.
  • There are several good threads on theServerSide [theserverside.com] about Eclipse [eclipse.org], NetBeans [netbeans.org], and IntelliJ IDEA [intellij.com]. Most of the posters there have used one of these IDEs.

    threads on NetBeans [theserverside.com]
    threads on IDEA [theserverside.com]

    Eclipse is a product [oti.com] of Object Technology International Inc. [oti.com], which also produced VisualAge for Java.

    And as the article "Refactoring with Eclipse" [ibm.com] mentioned, "...Erich Gamma is the team lead for Java tools for Eclipse. Gamma was one of the Gang of Four known for creating the book Design Patterns...". I think that Eclipse will be a high quality software.

  • Eclipse seems well thought out except for one thing - it's missing code completion. This is helpful for reallyLongMethodNamesInJava, for not having to look up api docs all the time to determine method calls etc.

    If someone can point me to a plug-in which rectifies this for Eclipse I would be grateful.

    Code completion is one of the reasons I am currently sticking with JBuilder 5 (though I am rapidly beginning to like Intellij IDEA, its refactoring support is awesome)

  • When I first tried Eclipse, I was very impressed.

    First of all, it looks good. Much better than any other Java program I tried.

    Second, it used a single main window instead of multiple floating ones. Us stupid Windows programmers find multiple floating windows visually confusing. There is nothing worse than seeing one's desktop bitmap with all those shiny icons in betweens one's editor and one's toolbar. (Even MDI is dying out as a concept and being replaced with a single window with tabs representing open files at the top. The only people still prefering MDI are traders, because they generally set their workspaces up to view as much info as possible and then just monitor them.)

    Third, it's the first well-made piece of software I've ever seen from IBM. IBM has a history of producing inferior software on the PC platform. I once heard someone from IBM refer to his colleagues as "ninjas". If they spent more time working on their programs and less time dressed in black pajamas throwing metal stars, maybe their code would be better.

    Fourth, the plug-in concept is well executed. Usually abstraction and usability don't go well hand in hand, but using Eclipse was just as comfortable as using JBuilder which is a Java-only IDE.

    So why an I not using Eclipse? Because their Java plug-in is still not robust enough.

    I had a rather large project that I was working on. It worked fine in JBuilder and JDK with Ant. But when I loaded those same files into Eclipse, simply touching some of them caused Eclipse to puke.

    Must have been some programming construct I used. But if a tool doesn't offer a simple migration path, most people are not going to switch. More to that point: Why can't Eclipse import JBuilder and Forte project files? That would also ease the transition.
