Its no fun when a low level Git function suddenly calls die() because it was fed invalid user input like a mistyped branch name. Your whole IDE shutsdown without a chance to save files. So that leaves you with three possible routes: * Use JNI and libgit.a Now you have three projects, not one. You first need to make libgit.a embeddable. *Then* you can work on a JNI wrapper, and finally you can build the UI. * Use jgit Its at least 100% pure Java and doesn't have the libgit.a issues I mentioned above. Its also got some active developers and its userbase is growing. We have been careful to keep jgit such that it runs on any J2SE system, and thus does not require an Eclipse environment. * Use java.lang.Process and pipes Ick. Forking a running JVM, especially one the size of an IDE, is not pretty. At least on Windows you have CreateProcess(), but on POSIX systems the JVM still does a fork/exec pair, and on Solaris that hurts hard when your address space is large. Of these only the latter two are really viable for any time to come (just my opinion, but that's that). jgit is coming along and may actually be able to do most of the critical features that an IDE demands, especially if more people work on it. The latter option is obviously available today, but doesn't offer anything near the performance or integration that jgit does. > 2. distributed versioned web system backup and restoration framework > (GPLv2 with CPE, same as NetBeans) > [I am not sure whether this one is even qualifies or not as a GIT > Community Project] > Language: Java, NetBeans RCP > Goal: Develop a framework which can backup and restore data from > different components of web application.

I don't doubt that we would have sufficient mentor experience here to support such a project, but the outcome in terms of both code and a student who is familiar with it would not benefit Git very well, if at all. -- Shawn.
