branch - 如何使用 JGit 创建 diff 分支？

Question

使用 JGit。需要知道分支的区别。
如何运行命令 JGit API:
git diff --name-status ..origin

Answer 1

您可以通过为分支创建 AbstractTreeIterator 实例来使用 DiffCommand，然后使用 DiffCommand 返回两个分支之间的差异列表:

// the diff works on TreeIterators, we prepare two for the two branches
AbstractTreeIterator oldTreeParser = prepareTreeParser(repository, "refs/heads/oldbranch");
AbstractTreeIterator newTreeParser = prepareTreeParser(repository, "refs/heads/master");

// then the procelain diff-command returns a list of diff entries
List<DiffEntry> diff = new Git(repository).diff().setOldTree(oldTreeParser).setNewTree(newTreeParser).call();
for(DiffEntry entry : diff) {
    System.out.println("Entry: " + entry);
}

现在可以找到包括创建 AbstractTreeIterator 的完整示例 as part of my jgit-cookbook
