Kotlin compile dependency

[PrzemyslawSwiderski]

Hi, I am using spring-cloud-stream in Java project and noticed that since 3.2.5 it has Kotlin in compile dependencies.
It is adding redundant Kotlin dependency to Java projects and can cause conflicts in Kotlin one.

Is this proper behavior? I cant see Kotlin beeing used in this lib extensively. Shouldn't it have a test or optional scope?
