Gerrit 触发器连接失败

【问题标题】：Gerrit Trigger Connection failsGerrit 触发器连接失败
【发布时间】：2014-09-24 15:19:44
【问题描述】：

我正在尝试让 Jenkins 的 Gerrit Trigger 插件正常工作，但是当我尝试测试连接时它继续抛出异常。我什至没有得到有用的错误消息。服务器错误日志也是空的。

由于 Stacktrace 中有一些 SSH-Stuff，我添加了我的 SSH 密钥文件。也许这可以帮助解决这个问题。

【问题讨论】：

  • 您是否尝试过先从 jenkins 服务器手动连接？
  • 你应该停止发布私钥;-)
  • 不用担心，这个密钥只是用于测试目的，以后不会使用...... :-)
  • 这篇文章对你有帮助吗？ stackoverflow.com/q/38761745/2394026

标签： ssh jenkins triggers connection gerrit


【解决方案1】：

您可以尝试按照以下说明在 windows 下设置 jenkins 的 ssh 密钥：http://blog.bruin.sg/2013/04/setup-ssh-key-pair-for-jenkins-under-windows/

【讨论】：

  • 当我启动我的 Git 安装的 bash.exe 时，它​​告诉我找不到 ssh-keygen 命令。
  • 它应该在您的C:\Program Files (x86)\Git\bin 文件夹中
