> Usage of "test-jar" is beneficial for all project, as all of them have tests.

> </plugin>
> Pom artifacts and some jar artifacts does not have test and will never have them.
> In logs we have: "[WARNING] JAR will be empty - no content was marked for inclusion!"
> and empty and useless artifacts are created, deployed , ...
> It will be convenient to have an plugin option to define whether skip empty jar creation and warning or generate jar with warning in log. Does it make sense ?
> By default option will be FALSE, to comply with previous behavior.
