Deleted files are not committed

Hi, I'm currently trying to modify and delete files in post release hooks. Modifications and additions are committed and pushed successfully. Files are deleted but I cannot manage to commit the deletions. Is there such a possibility to do it in post release hook? If not perhaps it would be possible to add a property 'all' to ScmProperties to propagate it to Git? I mean like this:

boolean isAll = properties.getAll();
jgitRepository.commit().setAll(isAll).setMessage(message).call();

That would be really helpful

Thanks a lot!
