isCoreLibraryDesugaringEnabled not works in gradle kotlin dsl / kts

Question

To enable desugaring in our android-library module we must put this in build.gradle:

android {
  compileOptions {
    coreLibraryDesugaringEnabled true
  }
}

But we have all scripts migrated to gradle kotlin dsl, so the problem occurs in build.gradle.kts in all three ways:

android {
    compileOptions {
        isCoreLibraryDesugaringEnabled = true
    }
}

configure<BaseExtension> {
    compileOptions {
        isCoreLibraryDesugaringEnabled = true
    }
}

android {
    if (this is com.android.build.api.dsl.LibraryExtension<*, *, *, *, *, *, *, *, *, *, *>) {
        buildFeatures.viewBinding = true
    }
}

Every time it throws Unresolved reference: isCoreLibraryDesugaringEnabled.

Does anybody have an idea how to fix this?

Answer 1

If you're using Android Gradle Plugin version >= 4.1, use:

isCoreLibraryDesugaringEnabled = true

For versions before that, use:

coreLibraryDesugaringEnabled = true
