I have this warning all over the place polluting our build logs, to the point where circleci is making me download our build logs because they are too long: This declaration is experimental and its usage should be marked with '@kotlinx.coroutines.ExperimentalCoroutinesApi'

Is there a way I can declare that we are using experimental coroutines api in the build.gradle, and thus get rid of all these warnings everywhere? Or am I forced to go to every file, and explicitly annotate it?

[gildor]

compileKotlin {
    kotlinOptions.freeCompilerArgs += ["-Xuse-experimental=kotlinx.coroutines.ExperimentalCoroutinesApi"]

}

[bdawg.io]

Experimental itself is an experimental feature. So you need to add "-Xuse-experimental=kotlin.Experimental" too

[gildor]

No, you don’t need it in this case, only if you want to have own experimental annotation and don’t want to have warnings

@gildor This doesn't seem to work for Android projects. The compileKotlin task doesn't exist. Any suggestions?

[gildor]

It does. Do you use groovy?

[gildor]

But maybe it has different name because of flavors

[Dico]

The -Xuse-experimental parameter, is that a list?

[gildor]

just use tasks.withType(KotlinCompile) to apply to all tasks of this type

[Dico]

Can I separate values by comma or something

[gildor]

yes, it’s list

[Dico]

Now I actually understand what it does, ty

[gildor]

kotlinOptions.freeCompilerArgs += ["-Xuse-experimental=kotlinx.coroutines.ObsoleteCoroutinesApi", "-Xuse-experimental=kotlinx.coroutines.ExperimentalCoroutinesApi"]

[spierce7]

hmmmm. Still didn't work.

tasks.withType(KotlinCompile) {
        kotlinOptions.freeCompilerArgs += ["-Xuse-experimental=kotlinx.coroutines.ExperimentalCoroutinesApi"]
    }

Could not get unknown property 'KotlinCompile' for project ':actions-android' of type org.gradle.api.Project.

[gildor]

Did you import KotlinCompile?

[gildor]

or just use fully qualified name org.jetbrains.kotlin.gradle.tasks.KotlinCompile

[spierce7]

I didn't. That was going to be my next question. what's the full qualified name

[spierce7]

thanks

[spierce7]

@gildor I'm seeing this error now: e: Experimental API marker kotlinx.coroutines.ExperimentalCoroutinesApi is unresolved. Please make sure it's present in the module dependencies

[gildor]

Do you have this error on compile time?

[spierce7]

yes

[spierce7]

compile time is the only time I see this error
