Multi module Gradle project Kotlin/Android - tests doesn't recompile

Hello,

I'm actually working on a Gradle multi-modules project, with Kotlin and Android modules inside.

If I mix a Kotlin & Kotlin/Android Gradle modules in my settings.gradle file,  then IntellIJ doesn"t recompile JUnit tests from Kotlin modules.

To reproduce it, checkout https://github.com/arnaudgiuliani/kotlin-android-modules and import it under IntelliJ 2018.1

Try to launch tests from core module. Modify it and relaunch it.

Any clue why if I had an Kotlin/Android module project IntelliJ react like that?
