java.lang.NoClassDefFoundError 异常：使用 JUnit 运行黄瓜测试时的 gherkin/util/FixJava

Question

我正在尝试使用 JUnit 运行黄瓜测试并遇到异常

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

非常感谢任何解决此问题的帮助

Answer 1

1. 您正在为 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。
2. 您正在显式导入作为传递依赖项的依赖项。从您的 pom.xml 中删除这些。
3. 您正在使用 非常 旧版本的 Cucumber。请使用更新的。

您可以在黄瓜文档中找到您需要的依赖项及其最新版本：cucumber.io/docs 下安装：https://cucumber.io/docs/installation/java/

Answer 2

方法是你下载gherkin-2.12.2.jar，gherkin-2.12.2-sources.jar 来自https://repo1.maven.org/maven2/info/cukes/gherkin/2.12.2/ 的文件并将它们添加到您的库中。
