Jenkins Slave显示为离线

我从以前的同事那里继承了詹金斯 . 不幸的是，他没有带任何其他人就这样做了，所以我对Jenkins的了解只不过是编写脚本并将它们放在仪表板中 . 如果我这样做的话，我会因缺少某些内容而道歉 .

本周我注意到有几个报告没有进来 . 当我跳上Jenkins仪表板时，it shows that the slave is offline . 我登录到安装了Jenkins slave的Windows服务器，我试图运行exe，并收到此错误：

Unable to Run Jenkins-Slave.exe

所以当我检查服务时，发现Jenkins服务没有运行 . 我试图运行它，我收到此错误：

Unable to Run Jenkins Slave Service

因为我真的不明白这个的来龙去脉，我不太清楚如何修复它 . 我尝试重新启动从站所在的服务器以及重新启动主站，但我没有得到任何更改 .

再说一次，我对此并不太精明，所以任何帮助都将不胜感激！

Edit: 评论员要求，这是我从日志中看到的信息 . 看看slave.out.log，我所看到的就是这样重复：

Both error and output logs will be printed to C:\Temp\JenkinsSlave\remoting

我在slave.err.log中看到了这个 . 这些是那里的最后一个条目 . 它们与位于C：\ Temp \ JenkinsSlave \ remoting的日志文件中的日志完全相同：

Edit 1: 所以，由于@MichaelPowers，我能够让奴隶回到网上 . 这是通过执行本文档中的步骤4完成的：How to Setup a node . 这使得奴隶重新上线，但我仍然无法运行与奴隶相关的工作 . 在日志中，我看到了这个：

还有另一种更新奴隶的方法吗？

Final Edit:

好消息，我想一旦能够让奴隶重新上线，我所要做的就是更新插件 . 我去了 Manage Jenkins > Manage Plugins 并且能够更新所有需要它的插件 . 重新启动后，我能够毫无问题地运行绑定到从站的作业 .

再次感谢您的帮助！
