Hello,
why do i get “Caused by: java.lang.NoClassDefFoundError: android/os/Looper” when trying to use coroutine on a Desktop target

The only dependency in my project in shared module is
implementation(“org.jetbrains.kotlinxkotlinx coroutines core1.7.1")

The code works fine in Android but crashes in Desktop

Looper is an Android thing. You must have some dependency on Android it.

@Alexander Maryanovsky I didn’t have any android dependency , but after adding
org.jetbrains.kotlinx:kotlinx-coroutines-swing
it got fixed

But this was kinda hard to find as it is hardly mentioned anywhere i guess

I think it is mentioned in the GitHub Wiki
