JGit API: How to generate diff against remote branch [message #659259]

We're currently evaluating using JGit to create some build tools. I've been playing around with the API and have gotten some of the basic things to work.

One thing I can't figure out, is how to generate a diff? I see a number of algorithms and diff classes in the package, but it isn't clear how to use them, at least in the way I need.

I've got a collection of repositories, and I want to scan through the repos looking for any of them that have changes in their index. I then want to be able to take a remote change list ID, and calculate a diff of all the files in the index against that remote changelist ID.

All the diff objects seem to focus on diffing two known files. Does JGit even support diffing a repository tree against a remote changelist?

Anyone point me in the right direction? Otherwise, I'll just be spawning GIT processes and parsing command responses Smile

We don't have a friendly API yet for Diff.

For now, I recommend you looking at how the CLI module handles things...

org.eclipse.jgit.pgm.Diff
