Sorry for the questions on this topic, but I believe the answer helps for documentation for this project.
as far as I understand this plugin reads only report files.
If I build an Android project with Kotlin via
./gradlew build
I have some output from the Kotlin compiler
(25, 17): Variable 'some' is never used
but I can't find any output with this text

Have any idea, how Kotlin Gradle output to integrate with the plugin?
