title: DexOverflowException after adding com.google.firebase:firebase-firestore:11.4.2
body: <p>I have a problem after adding compile "com.google.firebase:firebase-firestore:11.4.2" to my build.</p>
  
  <p>As soon as I add that, it also adds com.google.common among other things to my dex file, which is around 27k extra references, thus bursting through the 64k dex limit.</p>
  
  <p>Does anyone know why that is or am I doing something wrong?</p>
