title: Change name of generated war file and duplicate war file
body: <p>i want to set the filename of the war task output before it is deployed to repository.
  e.g. project name is <code>abc</code> and originally it would result in 
  abc-1.0.0-SNAPSHOT.war </p>
  
  <p>But i want that there should be two generated war files with the same content:</p>
  
  <ul>
  <li><code>def-1.0.0-SNAPSHOT.war</code></li>
  <li><code>ghi-1.0.0-SNAPSHOT.war</code></li>
  </ul>
