I was also getting the same error. Thanks to @Dominik for linking to the duplicate issue.

For now the work around is to downgrade com.google.gms:google-services to version 3.2.1 while the Android team works on a fix.

For today you can use

classpath 'com.google.gms:google-services:4.0.2'

Seems it works.
