从Eclipse运行Scala测试时发生异常

我下载了Scala IDE Linux - 64 bit For Scala 2.11.2并试图运行Scala测试。以下是我的代码。从Eclipse运行Scala测试时发生异常

package ppg.experiment.gameofbusiness.engine 

import org.scalatest.FlatSpec 
import org.scalatest.Matchers 

class DiceSpec extends FlatSpec with Matchers { 

    "A dice" should "roll a value greater than zero" in { 
    new Dice().roll > 0 
    } 
    it should "roll a value less than six" in { 
    new Dice().roll < 7 
    } 
}

当我点击右键并运行作为斯卡拉测试打印控制台

有人能告诉我如何解决这个问题，以下？

检查你的类路径;特别是检查你所依赖的scalatest版本是否为scala 2.11编译，而不是2.10。

你是一个天才！但你能告诉我你是怎么想出来的？ – 2014-11-02 17:50:42

只需阅读堆栈跟踪。一个'NoSuchMethodError'总是意味着调用不存在的方法的类（在本例中为'Runner $'）是针对方法不存在的不同版本的类进行编译的（在这种情况下，“$结肠$ colon'）。然后你可以查看这些类，看看它们分别属于scalatest和scala标准库。 – lmm 2014-11-03 00:09:42

顺便说一句，要做到这一点的方法是去你的项目和右键单击，然后属性> Scala编译器>选择适当的scala编译器>应用>确定 – grasshopper 2015-02-12 20:09:30
