Configuration on demand is not supported by the current version of the Android Gradle plugin

No need to downgrade!

Disabling configure on demand requires two steps:

1. Remove org.gradle.configureondemand from gradle.properties.

2. In Android Studio,
   For Mac go to the Preferences > Build, Execution, Deployment > Compiler and uncheck the configure on demand.
   For Linux/Windows go to the File > Settings > Build, Execution, Deployment > Compiler and uncheck the configure on demand.

Note, there are 2 gradle.properties files

1. In your project gradle.properties
2. ${HOME}/.gradle/gradle.properties

In Android Studio, just go to File -> Settings -> Build, Execution, Deployment -> Compiler and click to uncheck the configure on demand option, then click Ok and Sync Project with gradle files again.

I get same error after update to AS 3.1.2. You can still use Gradle version 4.6 but downgrade Android gradle plugin to 3.1.1

EDIT: just invalidate cache and restart
