@russhwolf the main problem of the new kotlin MPP is its lack of documentation. https://youtrack.jetbrains.com/issue/KT-27967

You're not wrong, but I've been messing with this stuff long enough that I'm used to it. There's more and more samples around that you can use as a guide but it definitely takes some understanding to get everything to fit together.

The problem is that for each step you have to dig: find some code somewhere, read the source, … Having an overview of the mechanisms and some simple examples (how to configurate the compiler) would help a lot.

The particular point of the compiler options is somewhat covered in the Setting up Targets section (http://kotlinlang.org/docs/reference/building-mpp-with-gradle.html#setting-up-targets). Though I agree that there's room for overall docs coverage improvements, so we'll keep improving the docs over time. Feel free to submit issues and docs pull requests for particular topics!

The place where the options are configured is mentioned but not the point that you need to use

compileKotlinJs

instead of the previous

compileKotlin2Js

. Some small exemples covering all the configuration possibilities would be enough for a lot of us: compiler configurations for all platforms, packaging, publishing, documentation.

Very much prefer the old plugin since its significantly easier to understand, more closely aligned with Gradle conventions/best practises, and it works with Gradle Kotlin DSL.
