title: Play application, how to reuse configurations in sub-projects?
body: <p>My Play application defines some project level configurations at the project root:</p>
  
  <p><code>/project/conf/resources.conf</code></p>
  
  <p>And I define some sub-project configurations:</p>
  
  <p><code>/project/modules/my_sub_project/conf/application.conf</code></p>
  
  <p>application.conf includes the parent resources with:</p>
  
  <p><code>include "resources"</code></p>
  
  <p>When I run my sub_project with:</p>
  
  <p><code>/project$ sbt run my_sub_project</code></p>
  
  <p>And retrieve configurations with:</p>
  
  <p><code>Play.application().configuration()</code></p>
  
  <p>The configurations from <code>application.conf</code> are loaded, but those in <code>resources.conf</code> are not.</p>
  
  <p>I have also tried the below include statements, but they have same result:</p>
  
  <p><code>include "resources.conf"
  include "../../../resources.conf"
  include "../../resources.conf"</code></p>
  
  <p>Any suggestion on how I should troubleshoot the project level configurations not loading? Any suggestions on how I should setup my project such that my sub-project can inherit configurations?</p>
