Eclipse JUnit 5 support

Currently, JUnit 5 is just out with a "stable" version. IntelliJ supports JUnit 5 according to the Website. My question is if eclipse is supporting JUnit 5 as well, and if not when it is going to be supported. With supported I mean if I can run JUnit 5 tests without the need for a @RunWith(PlatformRunner.class) annotation.

EDIT October 2017: Eclipse now officially supports JUnit 5 as of Eclipse Oxygen1.a (4.7.1a)

You can run JUnit 5 tests in Eclipse 4.7 Oxygen after installing the JUnit 5 Support (BETA) for Oxygen 4.7 plugin that you can find in the Eclipse Marketplace. After a complete Eclipse restart, open your project properties at

Java Build Path -> Libraries -> Add Library -> JUnit -> JUnit 5

quick note: make sure you are using the jupiter Test annotation (org.junit.jupiter.api.Test) and not the old junit.test (junit4). I wasted several hours trying to get my test to run on junit 5 because of this!

With Eclipse Kepler Service Release 2, you can run JUnit 5 tests after annotating the class with @RunWith(JUnitPlatform.class) as follows:

import static org.junit.jupiter.api.Assertions.assertEquals;
import org.junit.jupiter.api.DisplayName;
import org.junit.jupiter.api.Test;
import org.junit.platform.runner.JUnitPlatform;
import org.junit.runner.RunWith;

@RunWith(JUnitPlatform.class)
public class Junit5Demo {

    @DisplayName("First Test")
    @Test
    void firstTest() {
        assertEquals(1, 1);
    }
}

pom.xml of the project is as follows:
