I have a dependency issue in multiplatform project and I have prepared a minimum example to show it: https://github.com/micHar/kmm-dependency-issues/tree/master In short - cannot access multiplatform module classes in unit tests of a jvm-only module (NoClassDefFound). Would be super cool if someone could point me in the right direction. Maybe I'm doing something wrong or maybe it's a limitation or a new bug I can report. Please take a look guys.
