A modern programming language that makes developers happier.

kotlinlang

When I run `gradle build` in my project in IntelliJ IDEA, it runs fine (errors, but nothing special). But when I try to run a test in that same project by click on the green `run`-icon next to the test-method, it gives me this error: `Error:java: javacTask: source release 8 requires target release 1.8`
Seems like it runs JUnit tests not in the same way as gradle build? What should I change? I annotated it with `@kotlin.test.Test` and have `useJUnitPlatform()` in my gradle.build.kts in the test-section. How should I run tests fom IDEA?
