jenkins 主连接失败并出现 java.nio.channels.ClosedChannelException

Question

我有一个每小时运行一次的作业，从主机（Ubuntu 上的 Jenkins）到作为从机的 Windows 10 机器，30-40% 的时间作业会失败并出现以下错误。我需要一些帮助从哪里开始寻找或者可能的解决方案是什么。

Master和Slave都有相同的Java版本“1.8.0_151”

看来您在虚拟从属设备上使用秘密凭据时可能遇到问题。

从这里：

...最好的方法是创建一个 git 客户端身份验证令牌类，它使用 AuthenticationTokens.convert() 将特定凭据（用户名/密码或 ssh 私钥）映射到 git 客户端，然后 git 客户端身份验证令牌将被发送过来从主站到代理的线路，而不是通过线路发送 Secret。

也许尝试使用凭证插件？
