How to use GIT commands (diff, log, etc.) in Groovy script (windows)
提问by rock
I just started learning DevOps and have a query. It might be very basic so please don't mind.
我刚开始学习 DevOps 并有一个疑问。这可能是非常基本的，所以请不要介意。
Setup: Jenkins, GIT, Groovy, Java are installed on single windows server.
设置：Jenkins、GIT、Groovy、Java 安装在单个 Windows 服务器上。
My Goal is to write a Groovy script which will do following: 1. Execute GIT commands (on local GIT repository) to pull some data (result). 2. Take further actions based on above result.
我的目标是编写一个 Groovy 脚本，它将执行以下操作： 1. 执行 GIT 命令（在本地 GIT 存储库上）以提取一些数据（结果）。2. 根据以上结果采取进一步措施。
Query: How to execute GIT commands in Groovy script? What all is needed? Would be great if someone can please share a sample basic script.
查询：如何在 Groovy 脚本中执行 GIT 命令？什么都需要？如果有人可以分享一个示例基本脚本，那就太好了。

On a broader spectrum, what you want to achieve is just call linux commands from groovy, now regarding that:
在更广泛的范围内，您想要实现的只是从 groovy 调用 linux 命令，现在关于：
There are 3 ways out of this, either you can just call the git commands from a shell script (since i understand you want to use jenkins for this), use some sort of git jenkins plugin, or if you absolutely want to use groovy for it, you can take a look at this question Groovy executing shell commands, to summarize, you can do the following:
有 3 种方法可以解决这个问题，您可以只从 shell 脚本调用 git 命令（因为我知道您想为此使用 jenkins），使用某种 git jenkins 插件，或者如果您绝对想使用 groovy它，你可以看看这个问题Groovy execution shell commands，总结一下，你可以做到以下几点：
def proc = "git command args".execute()
def b = new StringBuffer()
proc.consumeProcessErrorStream(b)
println proc.text
println b.toString()
on b you would have the errors of executing the linux command if there were any,
在 b 上，如果有的话，你会在执行 linux 命令时遇到错误，
