运行Scalatest时NoSuchMethodError

Question

我创建了一个小程序，为了测试它，我编写了一个小Scala类。但是当我试图执行scala测试时，请告诉我，

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

Answer 1

我有决心了。谢谢你的回复。

我最夸张的版本出了问题。

我正在使用scalatest 11，而且scalatest版本与Scala版本不兼容。

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

上面的行添加了.sbt文件并刷新。现在，它运行良好，与预期的一样。
