I've looked around, and haven't seen anything about this, so I thought I'd ask.
I would seem to be really helpful if there were ANT tasks based on JGit. I know there are some that are wrappers for the exec command, but it would in my opinion be really useful for repeatable build scripts and such if there was a cross platform task for cloning and pulling repos.
If one exists and I simply missed it, I would be grateful to be pointed to it; if not then consider this a random idea.
Yes. We are currently moving from SVN to git. We handle a number of small(ish) projects and the overall git workflow is generally more to our liking.
Currently we have Hudson set up to run builds for our projects, which range in complexity from simply creating an archive from a set of PHP files, to building a simple RCP application. I also find it very useful if the builds can be made to run both on Hudson and from a developers workstation. For SVN I generally just used a property file to set the path to the executable. However, git support on Windows is, well less than optimal, and I am using the msys-git install running in its own shell. I could jump through some additional hoops and set that shell up so I can run ANT in it, but a solution that requires less configuration would be ideal.
