Scala SBT-Test.Setup抛出java.lang.ClassNotFoundException

我们目前正在使用SBT和Play做一个项目

我们希望将数据库旋转并只播放一次，以减少测试时间

SBT提供

测试。设置

和

测试。清理

来执行此操作

我在

test/util/TestServer.scala

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

要进行打印，我将其连接到SBT配置中：

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
这里有什么问题

我还尝试了
util.TestServer
和util.TestServer$class

，但给出了相同的错误

---

使用sbt版本0.13.0和Play 2.2.2

多亏了吉田健二，我发现了这个问题

这确实是Play框架引入的“fork”模式。您必须将其设置为false，才能使其与这些版本一起工作。

哪个版本的play2和sbt？使用sbt 0.13.0和play2.2.2
