Kotlin reflection implementation is not found at runtime

[john-black-3k]

I have the following code which uses reflection:
https://pl.kotl.in/iT267HMv-

It fails to run with the following exception:

Exception in thread "main" kotlin.jvm.KotlinReflectionNotSupportedError: Kotlin reflection implementation is not found at runtime. Make sure you have kotlin-reflect.jar in the classpath

Thank you in advance!
