If I have two KotlinJS projects, and one is a library that’s publishing a JAR containing JS to MavenLocal, and the other is an application consuming that library…how do I make it so I can “attach sources” in the application?

The library’s JAR looks like this:

- library.js
- library.js.map
- library.meta.js
- library/root-package.kjsm

The application can compile just fine against the library, but if I try to Go To Source on the library methods I get the decompiler stub.

To answer my own question…you just publish your Kotlin sources as usual, as documented [here](https://docs.gradle.org/current/userguide/publishing_maven.html#publishing_maven:complete_example), in a `*-sources.jar`. I had to use `sourceSets.main.allSource` instead of `sourceSets.main.allJava`, though, for the sources JAR.
