title: How to create subprojects inside Play with Intellij?
body: <p>Currently I have the following Play project structure:</p>
  
  <ul>
  <li>PlayApp
  
  <ul>
  <li>modules
  
  <ul>
  <li>common</li>
  <li>sub_project_two</li>
  </ul></li>
  </ul></li>
  </ul>
  
  <p>PlayApp is marked as a module, dependent on common.</p>
  
  <p>modules is just a directory.</p>
  
  <p>common is a sub project(also a play app).</p>
  
  <p>sub_project_two is a sub project(also a play app), which is dependent on common.</p>
  
  <p>Unfortunately I cannot just right click on "modules" and create new module(play app) and move on. Currently, I literally have to right click PlayApp and create the new module then move it to "modules", and it is running into dependency issues in Intellij and failing to import the classes inside "common".</p>
  
  <p>What is the correct way of creating subprojects inside Intellij?</p>
