Question

当我尝试在带有Scala 2.13的IntelliJ（2019.1），Scala IntelliJ插件v2019.1.8中运行测试时遇到以下错误：

Exception in thread "ScalaTest-dispatcher" java.lang.NoSuchMethodError: scala.collection.JavaConverters.seqAsJavaListConverter(Lscala/collection/Seq;)Lscala/collection/convert/Decorators$AsJava;
    at org.jetbrains.plugins.scala.testingSupport.scalaTest.treeBuilder.ParallelTreeBuilder.getOrdinalList(ParallelTreeBuilder.java:21)

    at org.scalatest.DispatchReporter$Propagator.run(DispatchReporter.scala:248)
    at java.lang.Thread.run(Thread.java:745)

以下是我的Gradle依赖项：

dependencies {
    implementation 'org.scala-lang:scala-library:2.13.0'

    testImplementation 'org.scalatic:scalatic_2.13:3.0.8'
    testImplementation 'org.scalatest:scalatest_2.13:3.0.8'
}

当我将依存关系更改为Scala 2.12.x时，测试将在IntelliJ中正确执行而没有错误。这是怎么回事？

更新：插件版本2019.1.9中的fixed。

可能需要为2.13更新IntelliJ Scala插件。同时，尝试通过选择被测Edit configuration...下的复选框Use sbt和Use UI with sbt来解决问题。根据{{3}}：

此问题已在
中修复

2019.1 EAP＃2019.1.8.21

2019.2每晚

将在2019.2 EAP和2019.1新版本中很快推出

关于Gradle，请尝试配置为委派给Dmitrii Naumenko

删除现有的ScalaTest运行程序
转到Build, Execution, Deployment | Build Tools | Gradle | Runner
选中复选框Delegate IDE build/run actions to Gradle
选择Gradle Test Runner

为什么在IntelliJ中运行Scala 2.13测试而不是在Scala 2.12中运行时出现此错误？
