title: How do I get @ParametersAreNonnullByDefault to work?
body: <p>I've made several attempts at getting package annotation @ParametersAreNonnullByDefault to work for me in a maven project but with no success.
  Could someone share a link to a minimal/sample maven project where this is setup (or post the pom.xml and package-info.java and demo class)?</p>
  
  <p>I'm talking about having findbugs processor enforce it for me.</p>
