org.gradle.api.tasks.testing.Test::useJunit does not have correct type signature

[JLLeitschuh]

Expected Behavior

org.gradle.api.tasks.testing.Test::useJunit should have have the signature:

public void useJUnit(Action<JUnitOptions> testFrameworkConfigure)

This same problem exists with:

org.gradle.api.tasks.testing.Test::useTestNg

Current Behavior

Currently it has the signature:

public void useJUnit(Action<? super TestFrameworkOptions> testFrameworkConfigure)

Context

In order to configure the JUnitOptions in Kotlin you need to do this:

useJUnit {
    this as JUnitOptions
    excludeCategories("edu.wpi.first.shuffleboard.app.NonHeadlessTests")
}

Steps to Reproduce (for bugs)

Try using this code in any Kotlin project that has the test task configured:

tasks.withType<Test> {
    useJUnit {
        // The line below this won't compile.
        excludeCategories("edu.wpi.first.shuffleboard.app.NonHeadlessTests")
    }
}

Your Environment
