Hey my Intellij in latest version shows me the error message:

The feature "multi platform projects" is experimental and should be enabled explicitly

for a shared lib. But I do have in my gradle file this

targets.all {
        compilations.all {
            kotlinOptions {
                freeCompilerArgs = listOf("-Xmulti-platform")
            }
        }
    }

but the error does not go away. It is running fine but super annoying. Anyone know what todo?

It is a flag in

gradle.properties

but it says something about alpha state I think 🤔

hmm I found this in the multiplatform guide?

the code will compile but it will do nothing

Interesting I give that a shot. I looked at https://kotlinlang.org/docs/reference/mpp-dsl-reference.html#compilation-parameters

Reviving this question because I just ran across it too. I only get this when I ported my gradle to be multiplatform manually but a new one autogenerated does not have this problem

I am getting the Intellij warning (The feature “multi platform projects” is experimental and should be enabled explicitly) when I set

kotlin.mpp.enableGranularSourceSetsMetadata=true

in gradle.properties. The warning goes away when I remove that setting and reload gradle.

I should keep it if it works for you, it will be enabled by default in the future

Unfortunately it doesn’t work for me. For now the warning and red underlining of all expect keywords is too annoying.

I think I got that issue too, but I don't remember if I solved removing it TBH

Ah, I think I am talking about a different warning, which appears in CLI, but after 2 months I dont remember 😢
