A modern programming language that makes developers happier.

kotlinlang

so … as is the rule when asking for help online- moments later I stumbled to the solution. I had to specify the common project as expectedBy my jvm target- which is like the first step of any of this, but my jvm target _isn’t_ really providing any implementations, just sharing common classes currently

Yes, it’s a correct way. Actually, your JVM target provide some implementations - it depends on kotlin-stdlib, which in turn provides implementations (in particular, for String and Int ) for kotlin-stdlib-common
