我想使用JGit显示头部修订版的所有文件和文件夹的列表。我可以使用 TreeWalk 列出所有文件，但这不会列出文件夹。

以下是我到目前为止所拥有的：

public class MainClass {

    public static void main(String[] args) throws IOException {
        FileRepositoryBuilder builder = new FileRepositoryBuilder();
        Repository repository = builder
                .setGitDir(new File("C:\\temp\\git\\.git")).readEnvironment()
                .findGitDir().build();

        listRepositoryContents(repository);

        repository.close();
    }

    private static void listRepositoryContents(Repository repository) throws IOException {
        Ref head = repository.getRef("HEAD");

        // a RevWalk allows to walk over commits based on some filtering that is defined
        RevWalk walk = new RevWalk(repository);

        RevCommit commit = walk.parseCommit(head.getObjectId());
        RevTree tree = commit.getTree();
        System.out.println("Having tree: " + tree);

        // now use a TreeWalk to iterate over all files in the Tree recursively
        // you can set Filters to narrow down the results if needed
        TreeWalk treeWalk = new TreeWalk(repository);
        treeWalk.addTree(tree);
        treeWalk.setRecursive(true);
        while (treeWalk.next()) {
            System.out.println("found: " + treeWalk.getPathString());
        }
    }
}

答案 1

您需要将递归设置为 false（请参阅文档），然后像这样操作：

TreeWalk treeWalk = new TreeWalk(repository);
treeWalk.addTree(tree);
treeWalk.setRecursive(false);
while (treeWalk.next()) {
    if (treeWalk.isSubtree()) {
        System.out.println("dir: " + treeWalk.getPathString());
        treeWalk.enterSubtree();
    } else {
        System.out.println("file: " + treeWalk.getPathString());
    }
}

答案 2

Git 不跟踪自己的目录。您只能从从 TreeWalk 获取的路径字符串派生非空目录名称。

请参阅 Git 常见问题解答（搜索“空目录”），了解详细说明和可能的解决方法。
