我目前在Windows 2012上使用Jenkins 1.650，并将Jenkins的testing实例（从我的生产服务器克隆）升级到2.25。
作为其中的一部分，Git客户端插件从1.19.6升级到2.1.0，现在无法进行身份validation。
如果我再次降级这个插件，我的工作就完美了，但是使用升级后的插件运行时，作业会失败。 所有的错误输出都是一样的：

这里的答案总结在这里：
如何将使用GIT_ASKPASS的Jenkins Git插件更改为.gitcredentials
但总之，在Windows环境中，有Jenkins 2+的已知错误，读密码包含需要Windows在命令提示符下转义的字符。
我更改了Github帐户的密码，并解决了身份validation问题。
