If you use Dagger with Kotlin, please upvote the addition of 'Incremental Annotation Processing' to

kapt

, lack of which is currently preventing Kotlin projects benefiting from the latest incremental features in both Gradle and Dagger2: https://youtrack.jetbrains.com/issue/KT-23880

@darkmoon_uk Then why they are adding

afterEvaluate {
        extensions.findByName('kapt')?.arguments {
            arg("dagger.gradle.incremental", "enabled")
        }
    }

Who is 'they'? I would expect the code fragment you've presented to have no effect: It is known that

kapt

does not currently support incremental Annotation Processing.
