I made some research and come to the conclusion that I just need to choose the right compilation type (and, umd or commons) and a package.json!

I noticed that the new Kotlin/JS plugin actually builds a package.json somewhere in the root project build directory.

Which task generates it and how I retrieve it without brutally copying it at the end of the build?
