kotlinlang

Does anyone have issues with `kotlin.mpp.enableGranularSourceSetsMetadata=true` ?
While my MPP library builds totally fine, it's wreaking havoc in my IDE (be it IntelliJ or Android Studio) :
• `public` modifiers are labelled as redundant (but `exlicitApi()` it enabled, removing them fails the build)
• `commonMain` sources may import declarations from `java.*` , which is illegal
• `expect` declarations are marked as errors due to "Kotlin Multiplatform is an experimental feature"
If I remove this config flag, I only have errors indicating that some `expect` declarations have no implementation in a given platform.

It's been tricky for the IDE for some time. The situation has improved recently, but it'll depend on Kotlin version, IDE version, and library versions.

Kotlin version: 1.5.32
Android Studio version: Android Studio Arctic Fox | 2020.3.1 Patch 4
Kotlin plugin: 203-1.6.10-release-923-AS7717.8

Hope this will be fixed in the near future

Your kotlin plugin version is newer than the kotlin version. I would try bumping kotlin to 1.6.10. Also, Android Studio and Intellij sometimes fall a bit out of sync. But, yeah, hierarchical source sets can take some tweaking to clear up.
