Question

我正在尝试在Intellij Coummunity Edition 13.1.3中运行Scala测试（specs2）。我收到以下错误：

Connected to the target VM, address: '127.0.0.1:57980', transport: 'socket'

'Start' method is not found in MyNotifierRunner null

以下是sbt中的一段代码runnig，但在Intellij中失败了：

class ReportsDemographicsComponentTest extends Specification with ReportsComponents {

  "ReportsDemographicsComponent" should {

    s"return empty list of $DeviceStatistics for an inexistent deliveryId" in DBUnitTestsUtils(2) {
      accountId => implicit session =>

        val service = new ReportsDemographicsService(accountId)
        val res = service.deviceStatistics(-1)

        res.size mustEqual 0
    }
}

我已经尝试重新启动Intellij，sbt，清理项目，但努力取得成功。当从sbt命令行进行runnig测试时，一切正常。有什么想法吗？

在我的案例中关闭Idea并通过发布

重新生成项目步骤

sbt gen-idea

注意：您必须将此行放入project/plugins.sbt以获得命令：

addSbtPlugin("com.github.mpeltonen" % "sbt-idea" % "1.6.0")

在Intellij中运行Scala测试
