  </code></pre>
  
  <p>Here's the Ant task:</p>
  
  <pre><code>&lt;flexunit swf="${APP_BIN_DIR}/UnitTestingApp.swf" timeout="5000" toDir="${APP_REPORTS_DIR}" haltonfailure="false" verbose="true" localTrusted="false" command="${FLASH_PLAYER}" /&gt;
  </code></pre>
  
  <p>I gave 777 permissions to <code>${APP_BIN_DIR}</code>, <code>${APP_REPORTS_DIR}</code> and <code>Flash Player Debugger.app</code> but that didn't change anything. I also tried running the command <code>sudo ant</code> but that too had no effect on the error.</p>
