检查8080端口时，输出为

$ lsof -i:8080
$ lsof -i:80

我的问题

为什么会出现此错误以及如何消除此错误？

Tomcat在端口8080上运行。可以通过在浏览器中键入

localhost:8080

来检测

令人惊讶的是，

lsof-i:8080

无法检测到它。

您是否在运行构建过程两次？因为它第一次失败，我重试了$mvn jetty:run。当然，在同一端口上运行的其他进程，正如kayaman所说，可能是jetty服务器。它可能不一定是jetty。事实上可能有很多事情。在最坏的情况下，点击

打碎玻璃并重新启动机器：）我还会尝试“netstat-tulpen”或“ps-u gaurav”来查看是否有构建挂起。但这很奇怪。您尝试重新启动了吗？下次我会尝试使用提升的权限运行它。如果有疑问，请尝试telnet到本地主机8080。很高兴你找到了！
