Question

我现在有这个问题3天了，我不知道怎么解决它... 这里是：我正在使用Cucumber和Maven进行验收测试。

我的所有测试都运行良好，我创建了一个jar库，我将其作为依赖项导入到我要测试的项目的pom.xml文件中。

一切顺利，直到我刚刚更改了我导入的jar的groupID的名称......

然而，我做了一个＆＃34; mvn install＆＃34;我想要导入我的项目的命令，然后再次运行我的项目进行测试（显然我在pom.xml文件中更改了依赖项）。

我现在得到的错误是：

只是一个信息（可能是我的错误来自）：我正在使用jar文件来读取我想要测试的项目中的属性。

如果您有任何想法，我会很高兴听到它...... 谢谢！

Answer 1

找出问题的来源：

我正在使用org.jdom依赖，而jdom从未被识别，并且永远无法实例化（有点奇怪，但我无法解释它......）。我使用的解决方案是将jdom依赖性改为jdom2依赖。有了这种依赖性，一切都运行良好（暂时）。

CucumberException无法实现类
