[仅需一步][org.eclipse.jgit]Java代码操作git命令的步骤...再也不用手写git命令了

1.背景原因

linux跑了一个需要经常pull代码的java项目…
每次从gitee拉代码无论是用.sh还是直接命令行都很麻烦而且担心搞错分支…

2.开源库jgit

org.eclipse.jgit

3.上手使用

pom.xml

<dependency>
    <groupId>org.eclipse.jgit</groupId>
    <artifactId>org.eclipse.jgit</artifactId>
    <version>5.12.0.202106070339-r</version>
</dependency>
