title: Maven install iff changes exist
body: <p>I was wondering if there is a way to determine whether changes were made to the project and run <code>mvn install</code> only in that case. Similar to <a href="https://stackoverflow.com/q/15405413/4828060">this question</a> but I am not very interested in incremental build - Ideally I would like the build command to do nothing if no changes were made in the project. Is this possible</p>
  <p>Thank you for your help.</p>
