AAR plugin on Kotlin

Hi !
I'm creating aar library for unity, that uses Kotlin. I've successfully added all dependencies via GoogleJarResolver. (see recommendations also here https://forum.unity.com/threads/aar-library-with-kotlin.515272/ )
But also I need to
1) add

Code (Boo):

1. apply plugin: 'kotlin-android-extensions'
2. apply plugin: 'kotlin-kapt'

in the beginning of build.gradle file.

2) Add one library not like "implementation" , but as "kapt" (kotlin annotation processor)

How can I do it?
