title: Call ant target multiple times with different parameters
body: <p>Is it possible in Ant to call the same target multiple times with different parameters?</p>
  
  <p>My command looks like the following:</p>
  
  <pre><code>ant unittest -Dproject='proj1' unittest -Dproject='proj2'
  </code></pre>
  
  <p>The problem is that unittest gets run twice, but only for proj2:</p>
  
  <pre><code>unittest:
      [echo] Executing unit test for project proj2
  
  unittest:
      [echo] Executing unit test for project proj2
  </code></pre>
  
  <p>I know that I can run two separate ant commands, but that is going to cause additional problems with the unit test report files.</p>
