title: Eclipse 3.7 runs auto build before executing ant task
body: <p>My Project -> Builders list looks like this:</p>
  
  <ul>
  <li>Ant</li>
  <li>Android resource manager</li>
  <li>Android pre compiler</li>
  <li>Java builder</li>
  <li>Android Package manager</li>
  </ul>
  
  <p>"Build Automatically" option is turned off</p>
  
  <p>If I run ant target from Ant view or as external tool then Eclipse makes this:</p>
  
  <ol>
  <li>It builds my project (it runs all builders from the builders list)</li>
  <li>Executes selected target</li>
  </ol>
  
  <p>If I remove Ant from builders list it executes only selected ant target (that's what I want).</p>
  
  <p>How can I make Eclipse launch only selected ant target without running other builders and without removing ant builder from the builders list?</p>
