I just wasted a bunch of time figuring out why adding https://search.maven.org/artifact/com.ensarsarajcic.kotlinx/serialization-msgpack/0.5.5/jar to my pom.xml didn't allow me to import the classes. Turns out it's full of .knm files, not .class files, and I needed the ...-jvm artifact instead. I guess this is a multiplatform thing? Is there some faster way to tell which dependency I need for JVM stuff, or is it just guess and check?

Might not be the answer you want, but Gradle should be able to pick the right variants automatically

[Tim McCormack]

Yeah, I tried Gradle for a while, but I ended up going back to Maven because the Gradle build script API was really poorly documented.

Yes. Simply speaking we publish in main publication references to platform specific publications as in the example above -jvm.

In Gradle metadata file in publication you could find what is the expected publication specific for the platform.

ideally your consumer would understand Gradle module metadata and it would all work out, but the library does have a way to update the multiplatform POM so that naive Maven resolution gets redirected to the JVM artifact
