title: How to auto reload app engine dev server?
body: <p>Im following the <a href="https://developers.google.com/appengine/docs/java/endpoints/getstarted/backend" rel="noreferrer">tutorial on the App Engine website for 'Google Cloud Endpoints' in Java</a>. Everything works fine and I can run the development server using <code>mvn appengine:devserver</code>. The problem is that when I make any changes to a file (for example, any java file) the dev server doesnt automatically recompile. I need to ctrl-c to kill the dev server and restart it for every code change I make.</p>
  
  <p>Is there a way to have maven automatically detect changes to any files in my project and have it automatically rebuild and restart the dev server? </p>
