【中文标题】JSF Maven Tomcat App突然从eclipse停止工作【英文标题】：JSF Maven Tomcat App suddenly stopped working from eclipse 【发布时间】：2012-10-05 01:26:29 【问题描述】：这快把我逼疯了。任何建议表示赞赏。
我的应用程序多年来一直在 Tomcat 7 上编译和运行。我直接从 Eclipse 运行它，并作为一个战争文件传输到 Tomcat 目录。现在出现以下错误，无论我是从 eclipse 运行应用程序，还是通过复制 war 文件。
应用突然停止运行。错误消息指出它找不到 Weld Listener 类。但是该类就在预期的位置，在 .m2 和 Tomcat webapp lib 目录中。
这是错误：

【问题讨论】：
【参考方案1】：您可能需要添加以下依赖项： 对于 Servlet 容器 (Tomcat/Jetty) 或 Java EE 5 应用服务器：Ref
<dependency>
<groupId>org.jboss.weld.servlet</groupId>
<artifactId>weld-servlet</artifactId>
<version>1.1.10.Final</version>
</dependency>
这个thread 可能有用。
【讨论】：
成功了，谢谢！我不知道为什么该应用程序在没有这种依赖关系的情况下工作了很长时间。此外，Eclipse 拒绝下载这个 jar - 相反，它具有基本上破坏 Maven 下载的“lastUpdated”文件。 Maven 是最脆弱的软件——我很乐意回去把它从项目中取出。无论如何，感谢您的帮助！以上是关于JSF Maven Tomcat App突然从eclipse停止工作的主要内容，如果未能解决你的问题，请参考以下文章
