Question

我正在尝试使用JUnit进行黄瓜测试并获得异常

java.lang.NoClassDefFoundError: gherkin/util/FixJava

RunnerClass：

import org.junit.runner.RunWith;
import cucumber.junit.Cucumber; 


    @RunWith(Cucumber.class) 
    @Cucumber.Options(
            features = ".//FeatureFile", //the path of the feature files
            glue= "StepDfb"
            )


    public class RunTest { 

    }

异常堆栈跟踪

我已将以下Cucumber jar文件添加到Eclipse，并将Cucumber插件添加到Eclipse

非常感谢您提供任何解决此问题的帮助

Answer 1

您要对Cucumber依赖项使用不同的版本。确保对所有Cucumber依赖项使用相同的版本，以防止出现问题。
您正在显式导入作为传递性依赖项的依赖项。从您的pom.xml中删除它们。
您正在使用非常的旧版本的Cucumber。请使用较新的版本。

您可以在黄瓜文档中找到所需的依赖项及其最新版本：cucumber.io/正在安装的文档：https://cucumber.io/docs/installation/java/

Answer 2

方法是您下载gherkin-2.12.2.jar，gherkin-2.12.2-sources.jar https://repo1.maven.org/maven2/info/cukes/gherkin/2.12.2/中的文件，并将它们添加到您的媒体库中。
