Jenkins上进行git相关配置

在Linux上搭建Jenkins后，配置git获取代码报错

主要报错有2个：

1、私钥配的有问题，导致没有权限从git上拉代码；

2、分支配的不对导致的错误

具体报错信息1：

genkins中git配置正确方法

有三个地方需要关注：

• Repository URL

  URL有2种方式https和SSH方式：

  ssh格式： git@github.com:panda-123/Jenkins_test.git

  https格式：https://github.com/panda-123/Jenkins_test.git

• Credentials

  本次使用的是SSH方式，设置证书时，选择SSH Username with private key

  Private Key中填写私钥，我的Jenkins搭建在Linux上的，私钥获取方式如下

  cd ~/.ssh
  cat id_rsa
  

• 指定分支

  查看自己git上的分支，然后修改为与之相同的就行
