Null pointer exception on pl.project13.maven:git-commit-id-plugin:2.1.5:revision

Hello,

I have a problem to build Flink master branch. Specifically, when I am
running "mvn clean install" in master branch I take the following
exception:

[ERROR] Failed to execute goal

It seams that no one else has this problem, especially with building the
master branch, so any help about how to get over this problem would be
highly appreciated!

I think Péter had a similar issue recently. Did you resolve it?

I'll look into it now ...

Re: Null pointer exception on pl.project13.maven:git-commit-id-plugin:2.1.5:revision

In reply to this post by F. Beligianni

I have the same problem on one of my computers but not on the other one.
I've read somewhere that it can be related to the git
version/configuration. I'm not completely sure, though.

Re: Null pointer exception on pl.project13.maven:git-commit-id-plugin:2.1.5:revision

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.

Re: Null pointer exception on pl.project13.maven:git-commit-id-plugin:2.1.5:revision

Thank you Robert,

I set useNativeGit to true just in flink-runtime package and the build was
successful :)

Just a comment I had to change also the version of the git-commit-id-plugin
to 2.1.10 which is the first version that has this configuration flag. The
version in the flink-runtime pom file was 2.1.5

Re: Null pointer exception on pl.project13.maven:git-commit-id-plugin:2.1.5:revision

But the version upgrade itself didn't fix the issue?

Re: Null pointer exception on pl.project13.maven:git-commit-id-plugin:2.1.5:revision

No, just the version upgrade didn't fix the issue.
Only after I upgraded the version to 2.1.10 and setting the flag
flink-runtime builds successfully.

The latest version of git-commit-id-plugin that can be used for the build
to be successful is the 2.1.13.
