当我对存储库中的第一个提交执行 git show commit
时,我看到了所有文件以及文件的差异(即添加的所有行)
$ git show cb5d132
commit cb5d13286cf9d14782f0e10445456dfe41072f55

似乎没有得到类似的信息,如何使用 JGit API 得到类似的输出?我可以使用 DiffFormatter
,但它似乎需要 baseTree 和 commitTree,想知道如何让 DiffFormatter
在存储库中的第一个提交上工作。
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());
最佳答案
使用 o.e.jgit.treewalk.EmptyTreeIterator
比较第一次提交:
AbstractTreeIterator oldTreeIter = new EmptyTreeIterator();
ObjectReader reader = repository.newObjectReader();
AbstractTreeIterator newTreeIter = new CanonicalTreeParser(null, reader, firstCommit.getTree());
List<DiffEntry> diffEntries = df.scan(oldTreeIter, newTreeIter);
...
关于jgit - 使用 JGit 显示没有父提交(第一次提交)的更改/差异,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/27739840/
