Difficulties running Ktor tests locally

Hello, since I’m waiting for being added to Ktor’s slack, I might as well ask here.

So I wanted to push a little PR, cloned the Ktor project, ran the ./gradlew build, the build succeeded.

However, I can’t just run tests from the IDE.

What the IDE says is:

Error:Kotlin: Experimental API marker io.ktor.util.KtorExperimentalAPI is unresolved. Please make sure it’s present in the module dependencies
Error:Kotlin: Experimental API marker io.ktor.util.InternalAPI is unresolved. Please make sure it’s present in the module dependencies

Kotlin version: 1.3.11
JDK: 1.8

Any other info needed?

Thanks for any help.
