SBT - Test.Setup throws java.lang.ClassNotFoundException

We are currently using SBT and Play to do a project.

We would like to spin upthe database and play only ONCE to lower the testing times.

SBT offers Tests.Setup and Tests.Cleanup to do this; http://www.scala-sbt.org/0.12.4/docs/Detailed-Topics/Testing.html

I've defined the following object in test/util/TestServer.scala

object TestServer {
  def start = println("hello")
}

To let this print I hook it up in the SBT config:

play.Project(name = appName, applicationVersion = appVersion, dependencies = appDependencies)
    .settings(
      // snip .. wiring resolvers and template/routes imports here
      testOptions in Test += Tests.Argument("junitxml", "console"),
      testOptions in Test += Tests.Setup(_.loadClass("util.TestServer$").getMethod("start").invoke(null)),
      testOptions in Test += Tests.Cleanup(_.loadClass("util.TestServer$").getMethod("stop").invoke(null)),
      scalacOptions += "-feature",
      doc in Compile

However when I run this, it complains about not finding the the TestServer class:

What is the problem here?

I've also tried util.TestServer and util.TestServer$class, but gives the same error.

Using sbt version 0.13.0 and Play 2.2.2

Thanks to Kenji Yoshida I found the problem.

It was indeed the "fork" mode introduced by the Play Framework. You have to set it to false in order to make it work with these versions.
