title: Android multidex not supporting with proguard
body: <p>I updated all my built tools, supportlibrary and google Play services.
  But still I am getting the following error:</p>
  
  <blockquote>
    <p>Error:Execution failed for task ':app:shrinkReleaseMultiDexComponents'</p>
    
    <p>java.io.IOException: The output jar [app\build\intermediates\multi-dex\release\componentClasses.jar] must be specified after an input jar, or it will be empty.</p>
  </blockquote>
  
  <p>I am able to fix this by setting <code>minifyEnabled</code> to <code>false</code>, but that is not what I want. Does anyone know how to fix it?</p>
