In gradle.properties I have this line

android.defaults.buildfeatures.buildconfig=true

In Build output I see this warning:

The option setting ‘android.defaults.buildfeatures.buildconfig=true’
is deprecated.

I tried to resolve this warning in Android Studio via Refactor > Migrate BuildConfig to Gradle Build Files

The line android.defaults.buildfeatures.buildconfig=true gets removed from gradle.properties, but no other project files are modified.

Question: What is “build Dsl” and where is it located?
