Hi guys. I recently started exploring the Kotlin repo and found a weird issue in the IDE. If I open the file `libraries/kotlin.test/common/src/main/kotlin/kotlin/test/Assertions.kt`, it says "Kotlin not configured" at the top and has a bunch of unresolved references. Now if I open the file `libraries/stdlib/samples/test/samples/collections/maps.kt`, it can't resolve function `assertTrue` and says that `import kotlin.test.*` is unused. I searched YouTrack but couldn't find a relevant issue. Does anybody know what this is? Thanks!
