[error] Uncaught exception when running UserTest: java.lang.NoSuchMethodError: org.junit.runner.Request.classes([Ljava/lang/Class;)Lorg/junit/runner/Request;

even an empty test case is not running.
public class UserTest {

Answer 1

It seems the classes method was added to the Request class on Junit version 4.6. I tried adding the following to the build.sbt file.
libraryDependencies += "junit" % "junit" % "4.8"
But it still didnt resolve the issue. Then I downloaded the jar and added it to the lib directory as an unmanaged resource. It seemed to do the trick and I am not getting any Errors now.
