I was just looking for a way to list all commits under each branch and I found this thread. I finally did something a bit different from some of the answers I found here and worked.

public static void main(String[] args) throws IOException, GitAPIException {
    Repository repo = new FileRepository("pathToRepo/.git");
    Git git = new Git(repo);

    List branches = git.branchList().call();

    for (Ref branch : branches) {
        String branchName = branch.getName();

        System.out.println("Commits of branch: " + branchName);
        System.out.println("-------------------------------------");

        Iterable commits = git.log().add(repo.resolve(branchName)).call();

        List commitsList = Lists.newArrayList(commits.iterator());

        for (RevCommit commit : commitsList) {
            System.out.println(commit.getName());
            System.out.println(commit.getAuthorIdent().getName());
            System.out.println(new Date(commit.getCommitTime() * 1000L));
            System.out.println(commit.getFullMessage());
        }
    }

    git.close();
}

Thanks for the help
