Does anyone know how to get a sibling java gradle module to be usable from Kotlin multiplatform? In the jvmMain source set I’m adding it as a direct implementation dependency, and the ide is telling me it can’t import those classes.

Might be you need to add

withJava()

to your target declaration. See https://kotlinlang.org/docs/mpp-configure-compilations.html#include-java-sources-in-jvm-compilations

good idea! I’ll give it a shot
