A modern programming language that makes developers happier.

kotlinlang

I see a  `compileKotlin` task when I build, although the project is pure java with kotlin libs, is it fine?

Do you by chance apply any of Kotlin plugins to your Gradle build?

yes, aren't they necessary for the runtime?

If so, even if there are no Kotlin sources, the task would still be there (and I presume would do nothing)

For merely consuming Kotlin libraries you shouldn't need Kotlin plugin.

I get an error if I do so, I'll try again on Monday
