Question

我试图运行一个简单的.feature文件，以便为Step文件生成所需的代码，但是返回以下异常：

下面是pom文件：

我发现了许多类似的问题，它们涉及NoClassDefFoundError异常，但它们与 gherkin / formatter / Reporter 相关，与 cucumber / api / formatter / Formatter 无关。

>

例如：java.lang.NoClassDefFoundError: gherkin/formatter/Reporter for Cucumber with extent reports

预先感谢

添加以下依赖项可能会有所帮助。

<dependency>
    <groupId>io.cucumber</groupId>
    <artifactId>cucumber-core</artifactId>
    <version>3.0.0</version>
</dependency>

java.lang.NoClassDefFoundError：运行.feature文件时，cucumber / api / formatter / Formatter
