Hello, I'm creating a JavaFX application base with Gradle, Kotlin and Dagger 2 and I'm trying to get kapt to figure out my ApplicationComponent, but all I'm getting is this warning from gradle:

w: [kapt] Sources output directory is not specified for app_main, skipping annotation processing

. How do I specify a sources output folder? I've done some Android programming previously and never had this problem, although this time my gradle project has multiple modules and no root project sources. Edit: nvm, found a working fix from here: https://github.com/griffio/dagger2-kotlin
