body: <p>I have a Cordova Android project, and I have added the <a href="https://github.com/fechanique/cordova-plugin-fcm" rel="nofollow noreferrer">Google Firebase Cloud Messaging Cordova Push Plugin</a></p>
  
  <p>I am getting the following error on the MyFirebaseMessagingService.java file.</p>
  
  <pre><code>The hierarchy of the type MyFirebaseMessagingService is inconsistent
  </code></pre>
  
  <p>and</p>

  <p>I have tried various combinations of removing and adding different jar files but no luck.</p>
  
  <p>Has anyone else come across this error before when adding this plugin? </p>
  
  <p>Thanks for any help. I can post more code or screenshots if needed.</p>
