    Description

      While working on broken links via RAT-353 I realized after adding the new maven-plugin-report-plugin a NPE breaks the build and no site-related pages are generated.

      Exception -> [Help 1]

      Thus there are no

      • plugin-info.html
      • check-mojo.html
      • rat-mojo.html
        in the site build, which prevents us from releasing RAT.

      (btw: would it make sense to add a new component in your Jira for
      maven-plugin-report-plugin?)
