Question

我在sbt-mult-jvm插件下面，该插件可以在sbt版本0.13.18上正常工作。

    import com.typesafe.sbt.SbtMultiJvm
    import com.typesafe.sbt.SbtMultiJvm.MultiJvmKeys.MultiJvm

    lazy val rootProject = (project in file("."))
    .settings(executeTests in IntegrationTest <<= (executeTests in Test, executeTests in MultiJvm) map {
    case (testResults, multiNodeResults)  =>
        val overall =
        if (testResults.overall.id < multiNodeResults.overall.id)
            multiNodeResults.overall
        else
            testResults.overall
        Tests.Output(overall,
        testResults.events ++ multiNodeResults.events,
        testResults.summaries ++ multiNodeResults.summaries)
    }).
    configs(IntegrationTest, MultiJvm)

但是当我使用迁移documentation on custom claims

将sbt版本更新为1.x.x时

    import com.typesafe.sbt.SbtMultiJvm
    import com.typesafe.sbt.SbtMultiJvm.MultiJvmKeys.MultiJvm

    lazy val rootProject = (project in file("."))
    .settings(executeTests in IntegrationTest := (( executeTests in Test, executeTests in MultiJvm).value) map {
    case (testResults, multiNodeResults)  =>
        val overall =
        if (testResults.overall.id < multiNodeResults.overall.id)
            multiNodeResults.overall
        else
            testResults.overall
        Tests.Output(overall,
        testResults.events ++ multiNodeResults.events,
        testResults.summaries ++ multiNodeResults.summaries)
    }).
    configs(IntegrationTest, MultiJvm)

我遇到了错误。

如何解决此错误？

Answer 1

答案在您提供的link中；特别是“针对TaskKey的元组扩展（应用和映射）”已删除。

替代方法是使用.value，从而无需使用地图。

您的项目应该看起来像这样（未经测试）：

import com.typesafe.sbt.SbtMultiJvm
import com.typesafe.sbt.SbtMultiJvm.MultiJvmKeys.MultiJvm

lazy val rootProject = (project in file("."))
  .settings(executeTests in IntegrationTest := {
      val testResults = (executeTests in Test).value
      val multiNodeResults = (executeTests in MultiJvm).value
      val overall = if (testResults.overall.id < multiNodeResults.overall.id)
          multiNodeResults.overall
        else
          testResults.overall
      Tests.Output(overall,
      testResults.events ++ multiNodeResults.events,
      testResults.summaries ++ multiNodeResults.summaries)
    })
  .configs(IntegrationTest, MultiJvm)

SBT：从0.13.8更新到1.x.x时，“值映射不是（sbt.TaskKey [sbt.Tests.Output]，sbt.TaskKey [sbt.Tests.Output]]的成员”
