Re: [tycho-user] NPE with tycho-buildtimestamp-jgit
I can't reproduce the problem. The project builds for me locally and generated version qualifiers match git timestamp as far as I can tell. 

Can you try with clean local repository?

Hello Igor,

I just cloned the repository in question and the stacktrace appeared.
Maybe there is a mistake in my parent pom (at the root).

    Have you committed the project in question to git repository? Are you
    able to provide small standalone example we can use to reproduce the
    problem?
