推荐答案

我不知道原因，但它是在从属计算机重新启动后或在计算机断开连接(很长一段时间)后发生的.

I don't know the reason but it happens after a restart of the slave machine or when the machine lost the connection (during a long period).

问题(在我的情况下)是进程java -jar slave.jar没有在从属服务器中运行. 要解决此问题，请尝试在Jenkins菜单中重新连接该节点，因此请转到:

The problem (in my case) was that the process java -jar slave.jar was not running in the slave. For solve it, try to reconnect the node in Jenkins menus, so go to:

管理Jenkins->管理节点-> YOUR_NODE->断开连接

Manage Jenkins -> Manage Nodes -> YOUR_NODE -> Disconnect

管理Jenkins->管理节点-> YOUR_NODE->启动从属代理

Manage Jenkins -> Manage Nodes -> YOUR_NODE -> Launch slave agent
