don't suppose anyone has explored integration with Sonar for code coverage? most of what I am seeing on the interwebz doesn't look promising.

I haven't tried it but if you use the sonarqube gradle plugin in the shared code module it should work?

i don't think it's nearly that straightforward, and my understanding is there are some compatibility issues with Kotlin in general.

Hmm.. yes you're right! This would require the sonarqube gradle plugin to support KMM
