ok I guess the mvn call prints all the WARNING messages to stderr, and the version to stdout, and we're reading both (instead of reading only stdout)

I can't reproduce it for the moment, but anyway even if we fix the jx-release-version to ignore the warnings, it won't fix the root issue and you might have other issues with different tools.
so you should really fix the root issue, which seems to be a wrong version of guice, see https://stackoverflow.com/questions/55492394/maven-an-illegal-reflective-access-operation-has-occurred for example
