我试图用JUnit进行黄瓜测试,并且我得到java.lang.NoClassDefFoundError
例外。
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:

我已将下面的Cucumber jar文件添加到Eclipse中,并将黄瓜插件添加到eclipse中 - http://cucumber.github.com/cucumber-eclipse/update-site。
我在SE中发现了一些类似的问题并尝试了那里提到的建议但是徒劳无功。我尝试将小黄瓜降级到较低版本,如下面的链接所示。但这并没有解决问题。
以下问题的答案建议添加相同版本的黄瓜jar文件。但是由于Maven存储库中可用的jar文件本身没有相同的版本,我不确定如何/在哪里可以下载相同版本的所有黄瓜jar文件。
非常感谢您解决此问题的任何帮助。
