当我在仓库中对第一个提交进行“ git show commit#”时,我会看到所有文件以及文件的差异(即,添加的所有行)
$ git show cb5d132

The “ jgit show”似乎没有获得相似的信息,如何使用JGit API获得相似的输出,我可以使用DiffFormatter,但似乎需要baseTree和commitTree,想知道如何获取DiffFormatter用于存储库中的第一次提交。
ByteArrayOutputStream os = new ByteArrayOutputStream();
DiffFormatter df = new DiffFormatter( os )
RawTextComparator cmp = RawTextComparator.DEFAULT;
df.setRepository(repository);
df.setDiffComparator(cmp);
df.setDetectRenames(true);
// wondering how to use the API if we do not have baseCommit.
List<DiffEntry> diffEntries = df.scan(??baseCommitTree??, firstCommit.getTree());
for (DiffEntry diffEntry : diffEntries) {
df.format(diffEntry);
}
System.out.println( df.toString() )
使用o.e.jgit.treewalk.EmptyTreeIterator
将第一次提交与以下内容进行比较:
AbstractTreeIterator oldTreeIter = new EmptyTreeIterator();
ObjectReader reader = repository.newObjectReader();
AbstractTreeIterator newTreeIter = new CanonicalTreeParser(null, reader, firstCommit.getTree());
List<DiffEntry> diffEntries = df.scan(oldTreeIter, newTreeIter);
