Forge reports exported package conflicts for kotlin reflect

This is my first time writing a mod using KFF and I've ran into an issue where Forge will throw an exception, complaining that my mod exports the same package as KFF: kotlin.reflect.jvm.internal.impl.load.java

I've made sure that I'm not shading any Kotlin stdlib, reflect or coroutine dependencies into my JAR along with okhttp and I can't seem to find where Forge's JiJ locator is finding these files.

Marking as duplicate of #86 since the root cause is the same

Have you checked the compiled JAR file for your mod with a ZIP viewer like 7zip? Make sure you aren't shadowing the dependencies and check META-INF/jarjar for Kotlin libraries.

Yeah, I double checked that nothing is being shaded or JiJ'ed in

If this is in IntelliJ, you'll need to exclude okhttp's transitive dependencies on Kotlin in Gradle.

I tried, the issue persists still.

Could you send a link to your mod's GitHub repository?

It's private. I could provide snippets of the build files if you'd like.
