Jenkins Slave 在构建过程中下线

在 Windows Server 2012 上安装了 Jenkins 1.651 主服务器和从服务器。从服务器专用于运行 Selenium 测试，但大多数时候它处于离线状态：

Build step 'Execute Windows batch command' marked build as failure
ERROR: slave-tester is offline; cannot locate jdk7

是什么原因导致了这个问题以及如何解决它？

可能的解决方案

基于此来源，堆栈跟踪的一部分：

at java.util.concurrent.Executors$RunnableAdapter.call(Unknown Source)
at java.util.concurrent.FutureTask.run(Unknown Source)
at java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source)

at java.lang.Thread.run(Unknown Source)

在办公室遇到同样的问题，将 jdk7 升级到最新的 oracle-jdk8 可以解决问题。

如果问题仍然存在：

  1. 请准确指出问题发生的时间，以便可以重现该问题
  2. 请添加导致问题的构建的 Jenkins 构建日志。也许是作业执行的某个特定任务导致了问题。
  3. 在构建作业时查看 Windows 任务管理器
  4. 请添加一次成功构建的日志和一次失败构建的日志
