运行Scalatest时出现NoSuchMethodError

我创建了一个小程序，为了测试它，我编写了一个小的Scala测试类。但当我尝试执行scala测试时，我发现错误如下，请告知

java.lang.NoSuchMethodError: scala.collection.immutable.$colon$colon.hd$1()Ljava/lang/Object;

我下定决心了。谢谢大家的回复

我最分散的版本有问题

我使用的是Scala版本11，scalatest版本与Scala版本不兼容

libraryDependencies += "org.scalatest" % "scalatest_2.11" % "2.2.1" % "test"

上面的行添加到.sbt文件中并刷新。现在，它工作正常。

尽量不要在Idea中运行测试，而是在SBT中运行测试。想法有时会把事情搞砸。
