RE: jgit merge question

Great - thanks so much for this feedback and link.  My merge needs are straightforward, so hopefully this will suit the need!

I have pulled the latest jgit updates and downloaded the four .java files that are referenced in your link.  I have added these to the directory structure for jgit in the following new folder: org.spearce.jgit/src/org/spearce/jgit/merge/

However, when I try to now make_jgit.sh I am getting a series of errors (pasted below) that appear to stem from not having the same underlying files.  Is it possible that I am not getting the most recent jgit release files?  Or am I misunderstanding how you expect these Merge files to be used?

Thanks again, David

David is probably talking about the 8 patch series I proposed to add a crude merge API to JGit. The patches are available here, based on the current JGit master:
