How do I do the equivalent of “git diff --name-status” with jgit?

Question

I want to get a list of changed/added/deleted files between revision XXXXXX and HEAD. This is what I have so far:

String oldHash = \"a97e5553e37a25bd1a3c99ea         


        

Answer 1

You can get the tree id for HEAD and the hash by calling:

ObjectId head = repository.resolve("HEAD^{tree}");

and for the revision id:

ObjectId old = repository.resolve(oldHash + "^{tree}");

Once you have the tree ids you can create the tree iterators and get the diffs:

ObjectReader reader = repository.newObjectReader();
CanonicalTreeParser oldTreeIter = new CanonicalTreeParser();
oldTreeIter.reset(reader, oldId);
CanonicalTreeParser newTreeIter = new CanonicalTreeParser();
newTreeIter.reset(reader, headId);
List<DiffEntry> diffs= git.diff()
                        .setNewTree(newTreeIter)
                        .setOldTree(oldTreeIter)
                        .call();
