Re: [tycho-user] NPE with tycho-buildtimestamp-jgit 
I'd say a bug in JGitBuildTimestampProvider#getRelPath is more likely,
but I would not exclude a bug in jgit either.

Hello Igor,

thank you for investigating. I'll try to debug it on windows. The
problem seems to be in jgit, what do you think?

TIA,
Marco

    The problem is windows-specific, everything works under osx and linux.

    tycho-buildtimestamp-jgit sources are in [1]

    Tycho development environment setup is documented in [2]. I did not
    review/try instructions on that page recently, however.

        Sorry, no luck.

        I did a clean git clone
        https://github.com/mlehmannm/__mlm-eclipse-ide-jsbuilder.git
        <https://github.com/mlehmannm/mlm-eclipse-ide-jsbuilder.git> and
        then

        cls && mvn -X clean package -Dmaven.repo.local=.maven > mvn.log

        The result is in the appended log file.

        Maybe I can debug it? Any hints how to do that? What sources (from
        where) do I need?

        TIA,

             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?

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