The ivy jar was showing up in "git status", but it's an expected build artifiact, so can be .gitignore'd.
This was fixed as a part of AVRO-314.
In subversion this is ignored via a property on lib, rather than on the top-level directory. We should generally align .gitignore entries and svn:ignore properties. The command 'git-svn create-ignore' is meant to do this. Does that work for you?
One-line trivial patch.
