title: Maven jetty plugin - delay when starting in background mode
body: <p>I start a jetty server on linux using </p>
  
  <p><code>nohup mvn jetty:run &amp;</code> </p>
  
  <p>to run it in background and to stay when I quit from the console. Usually (mvn jetty:run) it starts in seconds, but in this case it takes about minute to start. What can be the cause of such a delay?</p>
  
  <p>Stack trace</p>
