title: Maven plugin to handle licenses?
body: <p>As the Maven pom can contain license information, Is there some way that you could for example tell your build that "Apache v2" Licennses are ok, but GPL for example not and when you build Maven would return errors if needed dependencies have forbidden licenses and eventually ask you to accept unknown ones? </p>
  
  <p>I know that there are plugins available that create a report of all used licenses in a project, but I couldn't find a single one that actually allow you to define what's ok, what's not and to ask for confirmation if it doesn't know.</p>
