java.lang.NoClassDefFoundError：组织/ hamcrest /自描述使用Maven

我试图运行Junit从酱实验室webdriver的例子，但我得到以下错误，当我运行“命令mvn测试”：java.lang.NoClassDefFoundError：组织/ hamcrest /自描述使用Maven

java.lang.NoClassDefFoundError: org/hamcrest/SelfDescribing

这里是全pom.xml中：

该项目是由运行时创建：

我试图增加对hamcrest排除和使用JUnit 4.11也尝试过，但我一直从MVN依赖性越来越java.lang.NoClassDefFoundError: org/hamcrest/SelfDescribing

有什么建议？

由于错误是抱怨缺少hamcrest类，您是否试过简单地将hamcrest导入您的项目？ – blgt

您能否提供一个我们可以用来重现此问题的最小示例测试课程？ –

其他的一定是错的。我尝试了与你完全相同的东西，并且我得到了Hamcrest作为JUnit的依赖...正如预期的那样！ – SiKing

如何在你的pom中添加对hamcrest的依赖？

<dependency> 
    <groupId>org.hamcrest</groupId> 
    <artifactId>hamcrest-all</artifactId> 
    <version>1.3</version> 
</dependency>

另请参阅this related SO问题。

添加依赖不适合我。 – user3047479

我刚说：

<dependency> 
    <groupId>org.hamcrest</groupId> 
    <artifactId>hamcrest-library</artifactId> 
</dependency>

后

<dependency> 
    <groupId>junit</groupId> 
    <artifactId>junit</artifactId> 
    <version>4.10</version> 
    <scope>test</scope> 
</dependency>

，它在我的项目工作。
