Jenkins无法启动：无法在端口8080上监听

Question

我正在使用Jenkins，从昨天开始它已经停止工作。我看着Windows服务，它已被停止（以某种方式）。我重新启动了它，但此后它立即停止了。

我查看了从（C：\ Program Files \
Jenkins）运行服务的目录，并在其中打开了名为jenkins.out.log的日志文件。这就是它的意思

已修复-
适用于将来可能会遇到此问题的其他任何人。我用了这篇Techrepublic的文章，归结为

netstat -a -n -o | grep "8080"

了解如何找出哪个进程正在使用端口8080，然后在“任务管理器”中将其杀死，然后重新启动Jenkins，一切正常（到目前为止！）。
