When migrating my MP project (android+ios) to kotlin 1.4 I ran into a problem with publishing that seems to be related to coroutines 1.3.9 (the problem goes away if I use 1.3.9-native-mt).
The project has the following dependencies:

implementation "org.jetbrains.kotlinx:kotlinx-coroutines-core:1.3.9"
implementation "io.ktor:ktor-client-core:1.4.0"

It's the task compileIosMainKotlinMetadata that fails with the following error:
e: Could not find "kotlinx-coroutines-core_concurrentMain"

Anyone else seen this?

This is expected. concurrentMain is only there in the native-mt version, and new ktor depends on it.

[hultgren]

gotcha. could not find any doc about this unfortunately

[louiscad]

native-mt is still being polished

[louiscad]

If it didn't need it, it'd be the default

I experience same error while migrating kotlin to 1.4
but the problem doesn’t go away with 1.3.9-native-mt on multiplatform library.

when I rollback ktor to 1.3.2.
ktor classes isn’t recognized.

is there other solution or workaround?

FYI, I found the reason and reported to sqldelight

@hultgren have you managed to solve this issue? I am facing with exact same problem at the moment.

You have to use the native-mt branch of coroutines
