标签： java maven selenium junit

我试图从酱汁实验室运行junit webdriver示例，但是当我运行＆＃39; mvn test＆＃39;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：

创建的

mvn archetype:generate -DarchetypeRepository=http://repository-saucelabs.forge.cloudbees.com/release -DarchetypeGroupId=com.saucelabs -DarchetypeArtifactId=quickstart-webdriver-junit -DarchetypeVersion=1.0.7 -DsauceUserName=<USERNAME> -DsauceAccessKey=<KEY>

我已尝试为hamcrest添加排除项，并尝试使用junit 4.11，但我不断获得java.lang.NoClassDefFoundError: org/hamcrest/SelfDescribing

如何在你的pom中添加hamcrest的依赖？

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

另见this related SO问题。

我刚刚补充道：

<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>

它在我的项目中有效。
