Migrate from KAPT to KSP #1235

Is there an existing issue?

• I have searched existing issues

Use case

Android Gradle plugin 9.0 introduces built-in Kotlin support and enables it by default. That means you no longer have to apply the org.jetbrains.kotlin.android (or kotlin-android) plugin in your build files to compile Kotlin source files. With built-in Kotlin, your build files are simpler and you can avoid compatibility issues between AGP and the kotlin-android plugin.

KAPT plugin is not compatible with this and without it no code is generated.

Proposed solution

see https://developer.android.com/build/migrate-to-ksp

Alternatives

Temporary workaround is use a legacy kapt plugin from Google
