Question

我正在尝试遍历所有存在的提交来存储关于它的信息（作者，提交者，时间戳，文件......）。它工作得很好，但有时当前提交显示不存在的条目。我将它与GitHub上的原始提交和本地git repo的图形用户界面进行了比较。我的代码有问题或者以错误的方式思考它吗？

private void getInformation() {
    Repository repository = new FileRepository(path);
    Git git = new Git(repository);
    RevCommit oldCommit = null;
    DiffFormatter diffFormatter = null;
    RevWalk walk = null;
    boolean first = true;

    walk = new RevWalk(repository);
    walk.markStart(walk.parseCommit(repository.resolve("HEAD")));
    walk.sort(RevSort.REVERSE);

    for (RevCommit commit : walk) {

        if (first == true) {
            oldCommit = commit;
            first = false;
        }

        /* read the old and new commit ID to determine changes (method by Rüdiger Herrmann) */
        ObjectReader reader = git.getRepository().newObjectReader();
        CanonicalTreeParser oldTree = parseRawGitdata(git, commit, reader);
        CanonicalTreeParser newTree = parseRawGitdata(git, oldCommit, reader);
        diffFormatter = new DiffFormatter(DisabledOutputStream.INSTANCE);
        diffFormatter.setRepository(git.getRepository());
        diffFormatter.setDetectRenames(true);
        List<DiffEntry> entries = diffFormatter.scan(newTree, oldTree);

        if (!entries.isEmpty()) {
            for (DiffEntry entry : entries) {
                /* only .java class files are relevant */
                if (entry.getOldPath().endsWith(".java") || entry.getNewPath().endsWith(".java")) {
                    /* handle the current ChangeType... */
                    determineChangeType(entry, commit);
                }
            }
        }
        oldCommit = commit;
    }

    diffFormatter.close();
    walk.close();    
}

private CanonicalTreeParser parseRawGitdata(Git git, RevCommit commit, ObjectReader reader) {

    CanonicalTreeParser treeIter = new CanonicalTreeParser();
    ObjectId tree = git.getRepository().resolve(commit.getTree().getName());
    treeIter.reset(reader, tree);

    return treeIter;
}

我只想在当前的HEAD开始（或在更改订单后结束）。例如，从开源项目Apache Struts查看提交“ af50018f11d4fdfa8ac04a55f942a4973cb15c87 ”的DiffEntry，它包含大约1170个项目：

DiffEntry[MODIFY .gitignore],   
DiffEntry[MODIFY apps/pom.xml],   
DiffEntry[DELETE apps/portlet/README.txt],   
DiffEntry[DELETE apps/portlet/pom.xml],

DiffEntry[DELETE apps/portlet/src/main/etc/gridsphere/README-gridsphere.txt],

据GitHub称，auhor于2016年8月1日承诺（af50018f11d4fdfa8ac04a55f942a4973cb15c87） - 增加了76次，删除了17次。

为什么我的DiffEntry集包含的数据不是官方提交的一部分？

JGit是否也提供了泛滥先前数据结构的未提交数据？

JGit DiffEntry显示不存在提交的文件
