I have 2 multi-platform library projects A and B where B depends on A and both Android and iOS depends on B.
How can I make classes from library A visible to Android and iOS through library B?

[mbonnin]

mark A as an "api" dependency of B

[mbonnin]

B/build.gradle.kts:

dependencies {
  api(project(":a"))
}

Do I need to add import A too in my ios app or just import B ? I’m not able to use it 🤔 I’ll check on android

[mbonnin]

Ah, for iOS you'll most likely need to export in the framework too

[mbonnin]

let me check

I can’t see classes from project A on android either. I said project but I’m using package dependencies api("com.jeantuffier:statemachine:2.0.6") . My android app imports the shared library through a string dependency and the ios app through a manually built xcframework. Should api(...) still work in that case?

Might be a tooling issue? IntelliJ/AS are quite wobbly when it comes to multiplatform and completion

[mbonnin]

I'd focus on Android first (because the JVM tooling is usually a bit better), try to build the project and see if that works (even with red underlines in Studio)

[mbonnin]

If it does, you might have to make sure all your dependencies have an android() target

[mbonnin]

that helps the IDE sometimes

[jean]

My library A targets the jvm while library B targets android, that might also be an issue

[mbonnin]

I've definitely seen IDE issues with this (although I think it built fine IIRC)

[jean]

turned out I was simply missing the maven repo configuration in gradle, since the library is hosted on github. It works on Android an iOS now. Thanks for the help!
