Single JUnit5 test execution with Gradle

I tried to run only one test class from Gradle. I used these commands:

gradle -Dtest.single=Junit5Test test
gradle test --tests ru.tests.runner.Junit5Test

But it runs all of the project's tests. I need to run only one test class. Here is my class:

public class Junit5Test {

      public static void main(String[] args) {
        LauncherDiscoveryRequest request = LauncherDiscoveryRequestBuilder.request()
            .selectors(
                selectPackage("ru.tests.api")
            )
            .build();

        Launcher launcher = LauncherFactory.create();
        launcher.execute(request, new TestExecutionListener());
      }
    } 

It works perfect by right-click run. I use

• IntellijIDEA 2017.1.5,
• Gradle,
• junitPlatformVersion = '1.0.0-M6',
• junitJupiterVersion = '5.0.0-M6'
