How comes that `commonMain/kotlin` is recognized as a source folder and `androidMain/kotlin` is not?...

How comes that commonMain/kotlin is recognized as a source folder and androidMain/kotlin is not?
The Gradle view in IntelliJ also doesn't list any Android source sets 😞

The android target is a bit special. You have to configure it with the android gradle plugin. See one example here https://gist.github.com/Ribesg/95a172ceb2177d74cf5b15993d40092e#file-build-gradle-kts-L27-L34

That helps, thanks!

The folder is now correct, but IntelliJ still refuses to list the source set 🤔

[ribesg]

Well I don’t have the right icon but everything works and the contained kotlin folder is automatically marked as a source directory, so it’s enough for me

[Marc Knaup]

nope, file isn't checked for errors and source set isn't listed 😕

[ribesg]

The gist I linked is what I have and I have no problems. The sourceSet doesn’t show up in the Gradle tab either, but who cares. I have IDE support in it anyway.

[Marc Knaup]

Looks like that Android Studio is doing some non-Gradle magic here because it works there but not in IntelliJ 🙄

[Kris Wong]

well, AS does utilize the android gradle plugin, so that's not entirely surprising

[Marc Knaup]

I wonder if there is a way to force the Source Set to become visible to IntelliJ 🤔

[Kris Wong]

i had some other funny business when building with intellij at first. I had to check a box to force it to delegate to gradle in Preferences

[Marc Knaup]

val sourceSetToCompilationData = LinkedHashMap<KotlinSourceSet, MutableSet<GradleSourceSetData>>()
for (target in mppModel.targets) {
    if (target.platform == KotlinPlatform.ANDROID) continue

ugh!

[ribesg]

I’m not using AS.

[Marc Knaup]

I wonder what the difference is which causes that 😞

[ribesg]

androidMain already depends on commonMain

[ribesg]

You can also try to completely delete your IDEA project and reimport your Gradle project

[Marc Knaup]

tried already, didn't help though 😕

[ribesg]

I’m also using Gradle 5.2.1 and Android Gradle Plugin 3.2.1 because more recent versions of both are bugged

[Marc Knaup]

Yeah I saw that and tried 3.2.1 too. doesn't help either

[ribesg]

After rollbacking the android gradle plugin you need to clean your project (remove .gradle and build folders then invalidate cache and restart)

[ribesg]

Sorry, I meant Gradle 5.1.1, 5.2.1 is the buggy one

[Marc Knaup]

😵
I guess I'll just start over later today and check if that helps.
