Use JGit TreeWalk to list files and folders

Question

I\'d like to use JGit to display a list of all files and folders for the head revision. I\'m able to list all files using TreeWalk, but this does not list folders.

Answer 1

You need to set recursive to false (see documentation) and then walk like this:

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());
    }
}

Answer 2

Git does not track directories of their own. You can only derive non-empty directory names from the path string you get from the TreeWalk.

See the Git FAQ (search for 'empty directory') for a detailed explanation and possible workarounds.
