Oh, I missed that add part. But no SVN + GIT + CVS, I guess. I'm hoping to abandon SVN as well, but o course I"m not in control of other projects. I'll have to find a better solution for my sourceforge projects -- unfortunately Google Labs doesn't support Git.

(Specific example is that we build some plugins/features for Drools to wrap the plugins/features that the Drools team does themselves; rather than rebuild their code, I use Ant to fetch their latest binary build from their Hudson job, unpack it, and have it available against which to compile our stuff.) Ideally they'd just publish a p2 repo against we could resolve the target platform, but for now this works just as well.) You could do the same to fetch CVS sources if you wanted... but really, moving to SVN or Git would be an even better idea. :)

Yeah, I actually made the decision to use CVS over SVN if you can believe it just because of my experiences with robustness of SVN or lack thereof and because the rest of Modeling was using it..but now, with XText moving to Git I'll likely be following their lead. I am *not* *not* *not* going to get into Maven now, lol.

cheers,
