Android Studio 3.0 Beta 4 woes

I’ve stripped your sample and tried to run it with Android Studio 3.0 Beta 4 64-bit on Windows, but it fails with the following error:

"C:\Program Files\Java\jdk1.8.0_141\bin\java" ...
Exception in thread "main" java.lang.NoSuchMethodError: org.junit.platform.launcher.Launcher.execute(Lorg/junit/platform/launcher/LauncherDiscoveryRequest;)V

Process finished with exit code 1

From previous issues I’ve gathered that this release should work out-of-the-box with the preview editions of Android Studio. However, I’ve also tried the workarounds mentioned in JUnit 5 docs for IntelliJ IDEA without any luck.

Running from command line works fine:

I’ve attached the stripped project if it matters: android-junit5-sample.zip

Unfortunately no, but you can check the README for a solution to the problem, because I’ve come up with a workaround. Apply the android-junit5-embedded-runtime dependency as a separate entry in your dependencies and you can run the tests again.

No change with 3.0 Beta 5.
