Jenkins Slave 在构建期间离线

  • 772

在 Windows Server 2012 上安装了 Jenkins 1.651 master 和 slave。slave 专用于运行 Selenium 测试，但大多数时候它会离线：

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

    可能的解决方案

    基于此 source，堆栈跟踪的一部分：

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

    并且在办公室中遇到同样的问题，将 jdk7 升级到最新的 oracle-jdk8 可以解决这个问题。

    如果问题仍然存在：

    1. 请准确说明问题发生的时间，以便可以重现问题
    2. 请添加导致问题的构建的 Jenkins 构建日志。也许有一个特定的任务由导致问题的作业执行。
    3. 构建作业时查看 windows 任务管理器
    4. 请添加成功构建之一的日志和失败构建之一的日志

  2. 我删除了解决我的问题的文件 rm -rf /var/lib/jenkins/secrets/jenkins.slaves.JnlpSlaveAgentProtocol.secret

    信息：错误和输出日志都将打印到 /home/ubuntu/remoting <===[JENKINS REMOTING CAPACITY]===>channel started Remoting 版本：4.13 这是一个 Unix 代理警告：发生了非法反射访问操作警告：jenkins.slaves.StandardOutputSwapper$ChannelSwapper 对构造函数 java.io.FileDescriptor(int) 的非法反射访问警告：请考虑向 jenkins.slaves.StandardOutputSwapper$ChannelSwapper 的维护者报告此情况警告：使用 --illegal-access=warn启用进一步非法反射访问操作的警告警告：所有非法访问操作将在将来的版本中被拒绝已撤出的标准输出错误：无法加载密钥：jenkins.slaves.JnlpSlaveAgentProtocol.secret java.lang.Error：无法加载密钥: jenkins.slaves.JnlpSlaveAgentProtocol.secret
