I want to convert a Kotlin/JVM library to Multiplatform. The biggest amount of work is an Apache library, which of course is JVM only. I think the first step is to split the code into commonMain/jvmMain, and use expect/actuals to decouple from the JVM lib, and then I could look at expanding to other targets. That first step is a lot of repetitive work though. It’d be nice if there was a tool that would generate expect/actual functions for a Java lib - it would make the process easier and less error prone. There are tools for generating interop code for C and JavaScript libraries. Is there one that generates interop code for Java libraries?

You don't really want to have all functions be part of your API, right? Or maybe not exactly the same. I don't think it's possible to this automatically
