ssh - Teamcity SSH 私钥登录失败 : invalid privatekey

Question

我设置了从 Windows 代理连接到 Linux 的 SSH 登录，但 TeamCity 出现以下错误。

[New build problem] com.jcraft.jsch.JSchException: invalid privatekey: [B@5543cd

SSH Secure Shell 生成的 key 对连接服务器没有问题。

类似的问题是 here但这不是我的程序问题，而是 teamcity 的内部异常。

请注意，我的问题不是 GitHub VCS 连接问题。只是我的 Windows TeamCity 代理与 CentOS Linux 服务器之间的问题。

完整的堆栈跟踪如下。

对于来这里寻找 Teamcity 上“无效私钥”解决方案的每个人，解决方案是使用以下命令生成 key :

ssh-keygen -t rsa -m PEM

这是在 this page中指出的文档的
