Can anybody tell me how to properly set up a Compose multiplatform library project. There does not seem to be any specific template for that. If there is no better approach I would like to start from a Kotlin multiplatform library project created by the Idea “New project” wizard and then extend that to support Compose. Whatever I have tried so far there always seems to be something missing. For the time being support for Android and Desktop would be enough.

Follow the precompiled script plugin trail and just add missing targets.

Compose lib is no different than any other mpp lib. Just add compose plugin and dependencies.

I just checked this page and this is what I came up with.

Thanks to all. I’ll have to dive into that a bit more.

@Albert Chang Your example was maximally helpful 🙏. I could fix my library setup and everything works like a charm now.
There is one thing which I do not understand though. Why do you duplicate all the Compose dependency entries in the source set configurations? It does not seem to be needed (at least in my case). I only have them once in commonMain.

I'm specifying the jetpack versions for Android and jetbrains versions for desktop because it was a android-only library and I don't want to change the versions of the jetpack dependencies.
