title: Ant fails to build:"Compile failed; see the compiler error output for details."
body: <p>I have the same problem as in this two questions:</p>
  
  <ul>
  <li><a href="https://stackoverflow.com/questions/12617618/ant-compile-failed-see-the-compiler-error-output-for-details">Ant compile failed</a></li>
  <li><a href="https://stackoverflow.com/questions/8667798/compile-failed-see-the-compiler-error-output-for-details">Compile failed</a></li>
  </ul>
  
  <p>I've detected which line of code causes this issue.</p>
  
  <pre><code>org.apache.jmeter.protocol.http.proxy.gui.ProxyControlGui proxyControlGui =
                      new org.apache.jmeter.protocol.http.proxy.gui.ProxyControlGui();
  </code></pre>
  
  <p>This string is used in:</p>
  
  <pre><code>package org.apache.jmeter;
  
  public class JMeter implements JMeterPlugin {
  </code></pre>
  
  <p>ProxyControlGUI</p>
  
  <pre><code>package org.apache.jmeter.protocol.http.proxy.gui;
  public class ProxyControlGui extends LogicControllerGui implements JMeterGUIComponent, ActionListener, ItemListener, KeyListener, UnsharedComponent
  </code></pre>
  
  <p>If I comment this string - build is successful.<br>
  Compiler does not complain during developing in IDE.</p>
  
  <p>I need to know:</p>
  
  <ul>
  <li>what's the reason of such behavior?</li>
  <li>where to see log with details(I'm new with ant)?</li>
  <li>how rewrite code to avoid javac error?</li>
  </ul>
  
  <p>Log from running ant in CL:</p>
