Hello,
thanks for this detailed bug report and the reproducer (also thanks for your contributions to the maven ecosystem) :-)

Unfortunately I'm currently unable to reproduce this issue with the repository provided.
I tried various multiple combinations now that would yield the cryptic error in your case:

$ mvn --version

In general your current configuration uses the jgit-implementation. That is more or less git implemented in java.

When searching the jgit repository:
The message templates are defined in:

org.eclipse.jgit/resources/org/eclipse/jgit/internal/JGitText.properties:commitGraphChunkUnknown=unknown commit-graph chunk: 0x{0}

and the error you observe comes from:
https://github.com/eclipse-jgit/jgit/blob/b1cc74b75b771279d81de15833da514c71513648/org.eclipse.jgit/src/org/eclipse/jgit/internal/storage/commitgraph/CommitGraphLoader.java#L194.

I can only speculate about the meaning of this error and hence I have created a bug in the jgit repository (eclipse-jgit/jgit#12).

To avoid this issue you could use the native git binary instead of the java git implementation. To enable the native git binary add <useNativeGit>true</useNativeGit> to the plugin configuration.

I hope this helps.
