使用JUnit运行黄瓜测试时出现java.lang.NoClassDefFoundError异常

我试图用JUnit运行黄瓜测试，并且得到java.lang.NoClassDefFoundError异常。使用JUnit运行黄瓜测试时出现java.lang.NoClassDefFoundError异常

的JUnit代码：

package ctest; 

import org.junit.runner.RunWith; 

import cucumber.api.CucumberOptions; 
import cucumber.api.junit.Cucumber; 

@RunWith(Cucumber.class) 
@CucumberOptions(
features = "Feature" 
,glue={"stepDefinition"} 
) 

public class Runner { 

}

例外：

我已经添加了低于黄瓜jar文件到Eclipse，并加入黄瓜插件从THI链接到日食 - http://cucumber.github.com/cucumber-eclipse/update-site。
