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(compile in MultiJvm <<= (compile in MultiJvm) triggeredBy (compile in IntegrationTest))
.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)
但是当我将sbt版本更新为1.x.x时，我遇到了以下错误。
