git tag

git查看tag

git查看tag命令：

ershixiongdeMacBook-Pro:spring-boot zzs$ git tag

v2.2.0.M1

v2.2.0.M2

v2.2.0.M3

v2.2.0.M4

v2.2.0.M5

v2.2.0.M6

v2.2.0.RC1

v2.2.0.RELEASE

v2.2.1.RELEASE

git切换到tag

git clone整个仓库后，使用以下命令就可以取得对应tag的代码：

git checkout tag_name

此时git可能会提示你当前处于“detached HEAD” 状态。因为tag相当于一个快照，不能修改它的代码。需要在tag代码基础上做修改，并创建一个分支：

git checkout -b branch_name tag_name

上面命令的意思切换到指定的tag（tag_name)，并创建一个分支，本地重新命名（branch_name）。

以SpringBoot的版本为例：

git checkout -b tag-2.2.1.RELEASE v2.2.1.RELEASE

其中tag-2.2.1.RELEASE为本地命名，v2.2.1.RELEASE为github上springboot项目自身的tag命名。
