Converting to Kotlin, met with error

[urban ledge]

I'm working on a Java project and within this project I did my first try with Kotlin. I converted one class to Kotlin. However, upon running some code from that class it crashes and I get met with the following error: Caused by: java.lang.NoClassDefFoundError: kotlin/jvm/internal/Intrinsics
Here is my build.gradle.kts file: https://pastebin.com/Npn43iYg
Thanks!

if you are using Kotlin, you need the Kotlin stdlib

[urban ledge]

But I already have it don't I?

implementation(kotlin("stdlib-jdk8"))

Oh so it is a Minecraft plugin?

Make sure that the Kotlin stdlib is also included when running Minecraft

Could you clarify what you mean?
Apparently I need to shade it: https://www.spigotmc.org/threads/java-lang-noclassdeffounderror-kotlin-jvm-internal-intrinsics.333120/
However, I'm not quire sure how to do it with gradle, here's my code: https://pastebin.com/Npn43iYg
I'd appreciate any help!

I don't really know gradle but maybe try something like that: https://stackoverflow.com/questions/34343640/how-to-shade-a-transitive-dependency-in-gradle
