1.  创建一个多分支流水线项目

*  显示名称（不太重要）
 *  分支源（非常重要）,添加Git远程仓库的url，选择用户凭证（username/password, ssh private key）,行为选择发现分支、发现标签

*  填写jenkinsfile在git仓库的相对路径

 *  保存

1.  立即扫描多分支流水线![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXlhbmdfdGFuZw_size_16_color_FFFFFF_t_70 4]
2.  选择项目的版本号tag(标签)，本文以1.1为例开始部署
