I don't understand this error, I add the dependencies, the error message isn't super intuitive

Exception in thread "main" kotlin.NotImplementedError: Implemented only in JetBrains fork.
Please use `org.jetbrains.compose.ui:ui-util` package instead.

Share your common dependencies as code, the problem is related to use androidx dependency in CMP project, so you need to use jetbrains androidx fork in common, not only in desktop.

here what I have

val commonMain by getting {
            dependencies {
                // keep-sorted start block=yes
                implementation(libs.compose.foundation)
                implementation(libs.compose.runtime)
                implementation(libs.compose.ui)
                implementation(libs.kotlinx.immutable.collections)
                implementation(libs.kotlinx.serialization.json)
                implementation(libs.compose.ui.tooling)
                // keep-sorted end
            }
        }

Ok, share your libs version toml too because you use it 😂😅

I have a bunch of kmp modiles and a desptop app, some modules are used by android mainly built for android, they have androidx.compose.ui:ui dependencies, not jetbrain. I added jetbrain fork in the desktop app module (common) but still failing.

Do I need to add the jetbrain fork in every app dependencies as well?

[Jack Boswell]

Probably yes

[ebtokyo]

is it valid to have androidx.compose.ui:ui in androidMain and org.jetbrains.compose.ui:ui in commotMain from the same moduile?

[Jack Boswell]

I don't see what the value of that would be, and I'd expect conflicts at compile time, but you can try it and see I guess

[ebtokyo]

ok make sense, thanks for the help!
