PiTest failing in CI maven build with "Input byte array has wrong 4-byte ending unit" even with no source code changes

My CI build is failing during the org.pitest:mutationCoverage goal when pushing up new code. My patchset has no changes to any source code (just a new, empty commit), yet the following error is printed:

16:49:26 [ERROR] Failed to execute goal org.pitest:pitest-maven:1.4.0:mutationCoverage (default) on project common-scheduler: Execution default of goal org.pitest:pitest-maven:1.4.0:mutationCoverage failed: Input byte array has wrong 4-byte ending unit -> [Help 1]

I've enabled verbose logging for PiTest, and debug logging for maven, not seeing anything in the logs. Can't see anything similar with this error online either.

Plugin configuration is: 

<plugin>

</plugin>

I'm struggling to understand where the error is coming from, as it doesn't seem linked to any code changes at all, yet is happening on every new patchset.

Solution

  • Raised the question on the github for PiTest: https://github.com/hcoles/pitest/issues/629

    Issue was a corrupted history file. Cleaning out the environment and running again sorted things out.
