* Git doesn't consider old "Mac" line ends (CR) as new lines. As a result the blame operation will contain fewer lines than expected by SonarQube and analysis will fail. The solution is to fix line ends to use either Windows (CR/LF) or Unix (LF) line ends.
* JGit doesn't support .mailmap file to "clean" email adress during the blame
+* "Missing blame information..." can be caused by checking out with a partial / shallow clone, or using Git submodules.
