transformClassesWithDesugar build error after updating to AS 3.0 Canary 6

With Android Studio 3.1, com.android.tools.build:gradle:3.1.0 and gradle-4.4-all.zip this issue resolving with adding

android.enableD8.desugaring = true

in gradle.properties file.


I had that issue when moved to Android Studio 3.0

Ensure that you have same versions of firebase-core and play-services, e.g.:

 compile 'com.google.android.gms:play-services-ads:11.0.4'
 compile 'com.google.firebase:firebase-core:11.0.4'
