is there a way to do something like this for all modules in a multiplatform project?

// ignore these warnings
kotlin.target.compilations.all {
    allKotlinSourceSets.forEach { sourceSet ->
        sourceSet.languageSettings.apply {
            useExperimentalAnnotation("kotlinx.coroutines.FlowPreview")
            useExperimentalAnnotation("kotlinx.coroutines.ExperimentalCoroutinesApi")
            useExperimentalAnnotation("io.ktor.util.KtorExperimentalAPI")
        }
    }
}

do you want to apply such setting to all mutliplatform Gradle modules in the project?

[william]

@tapchicoma i want to apply it to all multiplatform and jvm projects

[tapchicoma]

try to add following in the root project `build.gradle.kts`:

subprojects { subProj ->
    subProj.plugins.withId("org.jetbrains.kotlin.multiplatform") {
        subProj.extensions.configure(org.jetbrains.kotlin.gradle.dsl.KotlinMultiplatformExtension::class) {
            targets.configureEach {
                compilations.configureEach {
                    sourceSets.configureEach {
                        with(languageSettings) {
                            useExperimentalAnnotation("kotlinx.coroutines.FlowPreview")
                            useExperimentalAnnotation("kotlinx.coroutines.ExperimentalCoroutinesApi")
                            useExperimentalAnnotation("io.ktor.util.KtorExperimentalAPI")
                        }
                    }
                }
            }
        }
    }
}

had to tweak it a little bit but this works!

subprojects {
    plugins.withId("org.jetbrains.kotlin.multiplatform") {
        extensions.configure(org.jetbrains.kotlin.gradle.dsl.KotlinMultiplatformExtension::class) {
            targets.configureEach {
                compilations.configureEach {
                    sourceSets.configureEach {
                        with(languageSettings) {
                            useExperimentalAnnotation("kotlinx.coroutines.FlowPreview")
                            useExperimentalAnnotation("kotlinx.coroutines.ExperimentalCoroutinesApi")
                            useExperimentalAnnotation("io.ktor.util.KtorExperimentalAPI")
                        }
                    }
                }
            }
        }
    }
}

thank you!

@william, @tapchicoma I used the provided code above but it gives warnings for the modules that doesn’t include the library

w: Opt-in requirement marker kotlinx.coroutines.ExperimentalCoroutinesApi is unresolved. Please make sure it's present in the module dependencies

This warning causes build fail if you define allWarningsAsErrors is there any way that we can suppress this warnings ?

[tapchicoma]

afaik no
