我正在尝试从酱料实验室运行junit webdriver示例,但是当我运行“ mvn test”时出现以下错误：
java.lang.NoClassDefFoundError：org / hamcrest / SelfDescribing
这是完整的pom.xml：

该项目是通过运行以下命令创建的：
mvn原型：generate -DarchetypeRepository = http：//repository-saucelabs.forge.cloudbees.com/release -DarchetypeGroupId = com.saucelabs -DarchetypeArtifactId = quickstart-webdriver-junit -DarchetypeVersion = 1.0.7 -DsauceUserName =< USERNAME> -DsauceAccessKey =< KEY>
我尝试为hamcrest添加排除项,也尝试使用junit 4.11,但是我一直在获取java.lang.NoClassDefFoundError：org / hamcrest / SelfDescribing
mvndependency：tree的输出：

有什么建议吗？
解决方法:
如何在pom中添加hamcrest的依赖关系？
<dependency>
<groupId>org.hamcrest</groupId>
<artifactId>hamcrest-all</artifactId>
<version>1.3</version>
</dependency>
