Subject Re: Null pointer exception on pl.project13.maven:git-commit-id-plugin:2.1.5:revision
Date Wed, 03 Jun 2015 14:50:01 GMT
It seems to be an issue of the eclipse egit module:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=351855,
https://www.eclipse.org/forums/index.php/t/361344/,
https://netbeans.org/bugzilla/show_bug.cgi?id=243088


>From reading the source code [1] it seems that the jgit tool is trying to
resolve a commit by its ID, which is null?

Can you try setting useNativeGit to true for both instances of the
git-commit-id-plugin (in flink-runtime and flink-dist). Maybe that resolves
the issue.
Also, can you do a "git log" and check if everything with your history is
correct?
Maybe git fsck and git repair are tools that can help as well.
