Why is “3rd-party Gradle plug-ins may be the cause” showing after updating Gradle to 3.1.0?

Question

After updating Gradle to com.android.tools.build:gradle:3.1.0, in the log I now see:

Folder E:\\WORK\\App\\car_android\\carapp\\build\\

Answer 1

I delete two folder app\build\generated\source\kaptKotlin\debug and app\build\generated\source\kaptKotlin\release ("debug" and "release") and add in gradle:

kapt {
        mapDiagnosticLocations = true
    }

then the project is sync without problem.
