1.20.1 ClassNotFoundException for Kotlin Stdlib when jarJar'ing a Kotlin Library?

[ByThePowerOfScience]

I made a Kotlin wrapper for Brigadier that makes the command builder actually tolerable and released it as a library on GitHub.  Problem is, I can't actually use it without getting "ClassNotFoundException: kotlin.jvm.internal.Intrinsics".  This means it can't find the Kotlin standard library.

I've confirmed that the jar is downloading correctly, all of the dependencies are resolved properly, it's embedded in my mod jar, and it's even being extracted by Forge at runtime.  But when the library's entry method is called, I get that error saying that it can't find the Intrinsics class.  This doesn't make sense in the slightest, since the mod that's calling the library method is also written in Kotlin: at this point in the load cycle, KotlinForForge has already been loaded, and the exact same Intrinsics class that it's complaining about was already called successfully immediately before this method call.

Does anyone know what's even happening and how I can fix it?

 

My library can be found at https://github.com/ByThePowerOfScience/BrigadierDSL, and my build.gradle is at https://github.com/ByThePowerOfScience/DungeonDesigner/blob/1.20.x/build.gradle.kts.
