@nathanfallet thank you for your ongoing contributions!

Just to clarify a couple of things:

1. Moving an existing Kotlin tutorial that uses the Java client is perfectly fine
2. Committing things like generated Gradle or Maven wrappers into this repo is also fine

However, I'm afraid these days we have to ask you @nathanfallet to sign our contributor CLA. It's under two pages long and uses a legally binding digital signing service.
