我相信Microsoft必须在1月16日至17日之间引入一个漏洞。我想知道其他人是否遇到过类似的问题并找到了解决方法。 基本上，我有一个项目，什么都没有改变，但是管道开始失败。
尝试从git中获取代码时失败。这是工作时以及当前的日志文件的一部分。

如您所见，两个日志文件之间的区别是（靠近底部），它是在尝试执行“ git checkout”的时候：
基本上，代理在执行git checkout命令时不再尝试指定分支名称（在我的情况下为master）。这就是为什么它不起作用。我唯一可以解释的是Microsoft在git checkout任务中做了一些更改，并引入了回归。现在，我看不到任何解决方法。
谢谢， 斯蒂芬。
答案 0 :(得分：1)
对于此问题，Azure Devops最近有multiple pipeline service degradation events，这可能就是您遇到上述问题的原因。
一些用户在1月17日左右遇到了类似的git checkout错误：Git checkout failed with exit code: 128。
在开发者社区论坛上类似的case中，用户使用github作为远程仓库，作为一种解决方法，他完全重新运行了管道（使用/ azp run）。这通常可以解决问题，但是非常耗时
此问题正在调查中，您可以对该票进行表决，并将您的情况作为评论添加到反馈中。如果该问题在解决之后仍然存在，我们的工程师将进行进一步调查。
