我正在尝试在Ubuntu 12.04中运行以下命令：

$ mvn jetty:run

并且出现以下错误

我的问题

为什么我会遇到错误，怎样才能解决这个问题？

由于第一次失败了，我重新尝试了 $mvn jetty: run。 - Gaurav Agarwal

肯定有其他进程在同一端口上运行，正如kayaman所说，可能是jetty服务器。 - Suresh Atta

它不一定是Jetty。实际上可能是很多东西。在最坏的情况下，按下“打破玻璃”按钮并重新启动机器 :) - vikingsteve

我也会尝试使用"netstat -tulpen"或"ps -u gaurav"来查看是否有构建挂起。但这很奇怪。你尝试重新启动了吗？ - wemu
MAVEN_OPTS是否已设置，如果是，则是否包含用于远程调试的参数，例如：-agentlib:jdwp=transport=dt_socket,address=<PORT>,server=y,suspend=n。如果是这样，请问端口号是否为8080？ - user944849

Tomcat运行在端口8080上。在浏览器中输入localhost:8080可以检测到它。

令人惊讶的是，lsof -i:8080无法检测到它。

下次我会尝试以提升的权限运行它。 - Philip Whitehouse

如果有疑问，请尝试使用telnet连接到localhost 8080端口。很高兴您找到了它！ - vikingsteve
