I’m trying to add arrow as a dependency on an older multiplatform project but I’m running in this issue

Error while evaluating property 'filteredArgumentsMap' of task ':compileKotlinMetadata'
   > Could not resolve all files for configuration ':metadataCompileClasspath'.
      > Could not resolve io.arrow-kt:arrow-core:1.1.2.
        Required by:
            project :
         > The consumer was configured to find a usage of 'kotlin-api' of a library, preferably optimized for non-jvm, as well as attribute 'org.jetbrains.kotlin.platform.type' with value 'common'. However we cannot choose between the following variants of io.arrow-kt:arrow-core:1.1.2:
             - iosArm32ApiElements-published

             - watchosX64ApiElements-published
             - watchosX86ApiElements-published

this is my commonMain

val commonMain by getting {
    dependencies {
        implementation("io.arrow-kt:arrow-core:1.1.2")
        implementation("org.jetbrains.kotlinx:kotlinx-coroutines-core:1.6.1-native-mt")
    }
}

Am I missing something here? I tried to add other multiplatform dependencies like ktor, and it did not have the same issue, it compiled just fine

Hey @jean,

I am not sure... Do you anything different from https://github.com/arrow-kt/Arrow-MPP-Template/blob/main/build.gradle.kts ?

Or a repo you could share?

[simon.vergauwen]

The Kotlin MPP is a bit strange sometimes. Hopefully it's not some issue between Kotlin versions.

[jean]

It’s in this repo https://github.com/jeantuffier/statemachine. The first thing I noticed compared to the template is the targets, I just use the ios() shortcut.

[simon.vergauwen]

I can reproduce it locally but not yet sure what the issue is 😕

[simon.vergauwen]

@jean it seems to be related to the kotlin.mpp.enableCompatibilityMetadataVariant=true flag.
We're investigating how to solve atm.

[simon.vergauwen]

Adding or removing that flag might fix your issue.
