title: running mvn exec in the background of remote server
body: <p>Trying to run <code>mvn exec:java -Dexec.mainClass.</code></p>
  
  <p>that run a long process (could take up to 16 hours) on EC2 but whenever I lose connection with the remote server, the process stopped. I was wondering if I can run this in the background that doesn't affect my connection with EC2 remote server. </p>
