Jenkins 无法找到 Cygwin

我的詹金斯工作失败，因为它给出了以下错误消息：

我在 Windows 上运行 Jenkins 并想运行此 github repo 中的脚本：https://github.com/y0u-s/test

我将 Jenkins shell 程序路径设置为：C:\cygwin64\bin\bash

我现在陷入了困境，我该怎么做才能解决这个问题？

好的，我将在几个地方发布此解决方案，因为这对我有用，而且这个问题出现在几个问题中。不幸的是，解决方案需要一些注册表编辑。

TLDR 解决方案：

- Make sure cygwin is installed
- Open regedit.
- Go to HKEY_LOCAL_MACHINE - SOFTWARE - Wow6432Node
- Right click on Wow6432Node New->Key name it Cygwin
- Right click on Cygwin New->Key name it setup
- Right click on setup New->String Value name it rootdir
- Right click on rootdir Modify set it to your cygwin folder mine was "C:\cygwin64"

推理

https://github.com/jenkinsci/cygpath-plugin/blob/master/src/main/java/hudson/plugins/cygpath/CygpathLauncherDecorator.java

这是 Jenkins 代码，用于说明它如何查找 Cygwin。第 115 行是 for 循环的开始，它首先在 SOFTWARE\Wow6432Node 中查找，然后在 SOFTWARE 中查找 Cygwin 目录。在我的例子中，我已经有了“SOFTWARE\Cygwin\setup\rootdir，但似乎找不到它。我猜想存在一些问题，它提前退出循环或没有正确检查 SOFTWARE 目录。使用上面发布的解决方案是解决这个问题的一个不愉快的解决方法。
