title: Change Maven debug port number on runtime
body: <p>I would like to change the port number of <code>mvndebug</code> from the default 8000 to another one.</p>
  
  <p>I know that I can change it via MAVEN_DEBUG_OPTS environment variable like this:</p>
  
  <pre><code>MAVEN_DEBUG_OPTS=-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=8000
  </code></pre>
  
  <p>But I would like to debug an aplication in two different windows paralelly.</p>
  
  <p>The source code copyed to two different folder.</p>
  
  <p>Any idea how to change the Maven debug port number in runtime?</p>
