$ mvn jetty:run
并收到以下错误

检查 8080 端口时，输出为
$ lsof -i:8080
$ lsof -i:80
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
chrome 4683 gaurav 122u IPv4 102461 0t0 TCP gaurav-VPCEA24FM.local:60146->stackoverflow.com:http (ESTABLISHED)
chrome 4683 gaurav 195u IPv4 93101 0t0 TCP gaurav-VPCEA24FM.local:54759->stackoverflow.com:http (ESTABLISHED)
我的问题
为什么我会收到错误以及如何消除这个错误？
Tomcat 正在端口 8080 上运行。可以通过键入来检测到localhost:8080在浏览器中。
令人惊讶的是lsof -i:8080无法检测到它。
