title: Create Google App Engine Project in Eclipse with Modules
body: <p>I have been writing a GAE app with Eclipse with Maven as suggested on cloud.google.com. Recently, I needed to use "backends" or a different set of instances to handle a certain task. I found out that "backends" have been deprecated in favor of "modules". I have spent the last couple of days trying to set up the project to use modules and have made very little progress. </p>
  
  <p>All I want to do is have different URLs dispatch to different sets of instances (using modules and dispatch.xml). Does anybody know how I convert my existing Eclipse project to do this? I am even willing to make a new project.</p>
  
  <p>I need my modules to:
  1) Use shared source code / classes from my original application
  2) Have different numbers of resident instances
  3) Honor the rules in dispatch.xml</p>
  
  <p>I would like my project to run within eclipse and use either gradle or maven.</p>
