The eclipse plugin should do it for you if you run : $ mvn eclipse:configur-workspace -Dworkspace=${path to your eclipse workspace} I haven't tested it yet though, but I can give it a try tonight and add to the wiki. 2.

For trunk you should only need javacc (at least that works for me). For older branches I believe you need them both.
