Hey friends, I'm trying out New MPP with 1.3.0 stable, and running into some weird issues when trying to run a test in the IDE.

Whenever I try running a specific test (from my commonTest sources) using the Play button in the gutter, I get Error:(1, 18) Kotlin: [my-module_jvmMain] Declaration annotated with '@OptionalExpectation' can only be used in common module sources. Tests run perfectly fine with ./gradlew :my-module:jvmTest though!

I have a couple methods annotated with JsName and JvmStatic, but they very clearly are in the common module sources. I'm using a standard fromPreset(presets.jvm, 'jvm') target.

Do I need to explicitly call useExperimentalAnnotation or enableLanguageFeature to use annotations marked as @OptionalExpectation? Or is this an IDE issue? If it's an IDE issue, is there a ticket I should be following?

This will be fixed in 1.3.20: https://youtrack.jetbrains.com/issue/KT-26489

As a workaround, try delegating build/run actions to Gradle (Preferences | Build, Execution, Deployment | Build Tools | Gradle | Runner), remove the old run configuration which runs that test and rerun it with the gutter icon: the IDE will use Gradle for running tests now

Awesome, thanks for the speedy reply. Just wanted to make sure I wasn't doing something wrong 😛
