title: Where do I put META-INF in Gradle?
body: <p>I'm following the Appsrox tutorial on how to <a href="http://www.appsrox.com/android/tutorials/instachat" rel="noreferrer">Create an Instant Messaging app using Google Cloud Messaging (GCM)</a>. The differences are that I use Android Studio instead of Eclipse, and <a href="https://gradle.org/" rel="noreferrer">Gradle</a> for build automation. I've tried to put META-INF inside 'src/main' folder but I got a warning from Google App Engine:</p>
  
  <blockquote>
    <p>Warning:No META-INF/persistence.xml files were found in the CLASSPATH of the current thread!</p>
  </blockquote>
  
  <p><code>EntityManager</code> crashes during the initialization process, cause it can't find 'persistence.xml'.</p>
  
  <p>I'm looking for a simple answer to what should be a simple issue: where do I put META-INF folder?</p>
