Hi @test_dev,

Welcome! After examination, it appears it is not our plugin where the issue occurs, so we would advise opening this issue on the plugin’s Github page. We don’t officially provide a Maven integration or support but that should be a good first step for you.

Thanks for your time here and let us know how it goes,
Jesse
