Installing leJOS RCX eclipse plugin on MacOS Lion

[nybblr]

Hey leJOSers,

I did lego windstorms as a kid, and now as a CS student picked them back up and am using leJOS instead. With some difficulty, I got leJOS 3.0.0 running (pulled from CVS) and configured on MacOS, to the point that I can compile and download programs to my RCX (had to modify lejosjc script with the -d32 flag so java will use the 32-bit jirtrcx), but I haven't had any success installing the Eclipse plugin for leJOS RCX on MacOS Lion.

FIrst, I tried the download link on the lejos homepage for the plugin, but that apparently had some issues so I downloaded from CVS here: http://lejos.cvs.sourceforge.net/lejos/

I nabbed the ldt-core, ldt-docs, ldt-feature org.lejos, and org.lejos.tools and packaged them for eclipse with the same structure as the linked plugin on the main site. Eclipse was fine with it and installed the plugin without complaints, but none of the installed features work. When I try to create a leJOS RCX project, I get the following warning:

The wizard also pops up an error (revealed after clicking "Details>>"):

The selected wizard could not be started.
Plug-in org.lejos.ldt.core was unable to load class org.lejos.tools.eclipse.plugin.wizards.LejosRCXProjectWizard.
org.lejos.tools.eclipse.plugin.wizards.LejosRCXProjectWizard


I have tried changing load paths, plugin paths/structure, manual compilation, etc. and have had no success. I did find that the org.lejos.ldt.core had no compiled JAR files, and only .java files (unlike some of the other plugin components) however I see no way to manually build the jar, and am not sure if that is causing the problem.

Any ideas? I know at one point I read that the Eclipse plugin was "Windows only", but that was 7 years ago, and Java plugins are presumably "write once, run anywhere" so I'd like to think otherwise.

Again, the lejos 3.0.0 distro IS working (that took 2 days =) ) and I can write programs in MacVim, but I really need Eclipse's autocomplete and Java intelligence. I'd hugely appreciate any help!

Thanks,

Can't you configure external tools in Eclipse?
In that way you should be able to use Eclipse in the same way as any other editor?

And for the intilicense you can add a external source. I don't have Eclipse installed on this computer and I don't remeber the exact name.
But it is possible!
