How to get a Kotlin only class using reflection in JVM?

I'm developing a gradle plugin and it needs to reflect over some kotlin classes to generate some code but they are not visible in JRE with the same name and I don't know how to access them correctly.

I know that in this case kotlin.Any becomes java.lang.Object, but how do I detect that in runtime?

fun getClassFromKotlinName(kotlinName: String): Class<*>{ // Maybe return KClass<*> too if easier
    return Class.forName(kotlinName)
}
fun main() {
    println(getClassFromKotlinName("kotlin.Any"))
}

This causes:

Execution failed for task ':generateJvmCommonSources'.
> java.lang.ClassNotFoundException: kotlin.Any

How can I solve that?
