I tried in a lot of ways to clone a repo with jGit (it works). Then, I write some archive in the repository, and tried to add all (a git add *, git add -A or something like it).. but it don't work. The files simple are not added to the staging area.

My code is like this:

    FileRepositoryBuilder builder = new FileRepositoryBuilder();
    Repository repository = builder.setGitDir(new File(folder))
            .readEnvironment().findGitDir().setup().build();
    CloneCommand clone = Git.cloneRepository();
    clone.setBare(false).setCloneAllBranches(true);
    clone.setDirectory(f).setURI("[email protected]:test.git");
    try {
        clone.call();
    } catch (GitAPIException e) {
        e.printStackTrace();
    }
    Files.write("testing it...", new File(folder + "/test2.txt"),
            Charsets.UTF_8);
    Git g = new Git(repository);
    g.add().addFilepattern("*").call();

What am I doing wrong? Thanks.

Exception while trying what with addFilePattern("."):

Exception in thread "main" org.eclipse.jgit.errors.NoWorkTreeException: Bare Repository has neither a working tree, nor an index

One easy way to debug this is to look at the tests of the AddCommand in the JGit repo: AddCommandTest.java

You will see that in order to add all files the pattern "*" is never used, but "." is.
And it is used in the test function named... testAddWholeRepo()(!)

git.add().addFilepattern(".").call();

The Exception:

Exception in thread "main" org.eclipse.jgit.errors.NoWorkTreeException: 
Bare Repository has neither a working tree, nor an index

is quite explicit: you need to add file in a non-bare repo.

See test method testCloneRepository() to compare with your own clone, and see if there is any difference.
