ScalatrSuite测试在sbt中总是失败，在IDE中运行测试时成功

在sbt中使用ScalatTest进行ScalatrSuite单元测试时，我遇到了一些问题

我正在使用的版本： 斯卡拉特拉：2.2.1 比例测试：1.9.1 ScalatTest:2.2.1 码头：9.0.2.v20130417 Scala:2.10.1 SBT:0.12.3

我必须扩展ScalatrSuite并重写baseUrl方法，因为Jetty v9+我假设有一些代码更改，其中getHost和getLocalPort已被重新分解，因此作为临时解决方法，我同时使用以下方法：

    trait TempScalatraSuite extends ScalatraSuite {

  override def baseUrl: String =
    server.getConnectors.headOption match {
      case Some(conn) =>
        val networkConn = conn.asInstanceOf[org.eclipse.jetty.server.NetworkConnector]
        val host = Option(networkConn.getHost) getOrElse "localhost"
        val port = networkConn.getLocalPort
        require(port > 0, "The detected local port is < 1, that's not allowed")
        "http://%s:%d".format(host, port)
      case None =>
        sys.error("can't calculate base URL: no connector")
    }
}

SBT始终失败，并出现以下错误：

我可以看到jetty服务器启动然后关闭，但我真的不明白为什么

提前感谢。

解决了这个问题，只需在SBT中设置一个选项，为JVM提供测试：

fork in Test := true,

测试之后进行得很顺利

fork in Test := true,
