title: Maven fails to parse POMs at jenkins
body: <p>I have this simple maven project, containing a few common test tools.
  It builds locally, but on jenkins I am getting this strange error (see below).</p>
  
  <p>Other info:</p>
  
  <ul>
  <li>It builds locally with maven</li>
  <li>Settings are the same as all our other jenkins projects (very basic)</li>
  <li>Other jenkins builds work just fine</li>
  <li>I tried removing the /root/.jenkins/workspace/testtools folder </li>
  <li>I tried deleting the build and giving it a new name</li>
  <li>The disk is not full</li>
  <li>I failed to find any useful infomation elsewhere regarding this specific problem. </li>
  </ul>
  
  <p>**</p>
