build-helper-maven-plugin: java.lang.IllegalArgumentException: version can neither be null, empty nor blank #83

I'm running into an issue with build-helper-maven-plugin in a project I'm attempting to build.

I was previously (roughly about a year ago) able to build this project without issue on this host.

I'm now getting java.lang.IllegalArgumentException: version can neither be null, empty nor blank. Others within the project can still build fine.

I've tried a fresh source checkout and purging my maven cache. I've also tried updating the build-helper-maven-plugin version used by the project to what I understand is the latest (3.0.0), no change.

Full build logs from both attempts are available here:

Hoping for some guidance on how to debug this.

Thanks in advance.

This appears to be maven related. Rolling back to maven 3.6.1 allows the project to build, under maven 3.6.2 the above errors happen, regardless of plugin version.

I've reported the same bug (#81) and created a pull request to fix it (#82), but it seems this project is unmaintained at this moment since no response to either the bug or pull request has seen any response in almost a month.
