  </code></pre>
  
  <p>So I set <code>JAVA_HOME</code> environment variable but no advantage. The error seems <strong>maven search java compiler in jre path, not in <code>JAVA_HOME</code>.</strong></p>
  
  <ul>
  <li><p><code>JAVA_HOME</code> is <code>C:\Program Files\Java\jdk1.6.0_05</code>.</p></li>
  <li><p>Installed JRE is <code>C:\Program Files\Java\jre1.6.0_05</code>.</p></li>
  <li><p>My <code>PATH</code> variable is:</p></li>
  </ul>
