title: excluding some classes from web-inf/classes
body: <p>I use maven-war-plugin to build WAR, and I need to exclude several WAR classes from web-inf/classes (that's GWT classes, they shouldn't get to server deployment).</p>
  
  <p>How can I do it in maven?
  I tried "warSourceExcludes", "packagingExcludes" with no success.</p>
  
  <p>Any simple and creative solution in maven is acceptable, I need it for a test project.</p>
  
  <p>thanks</p>
