git版本回退 - 技术栈

代码推送到远程仓库之后想回退并且不保留任何历史记录：

查看版本号信息git log：

bash 复制代码

git log
commit version_example1  (HEAD -> dev, origin/dev, origin/HEAD)
Author: xxx <email>
Date: xxx
   XXX注释
   
commit version_example2
Author: xxx <email>
Date: xxx
   XXX注释

回退git reset --hard 目标版本号

bash 复制代码

git reset --hard version_example2

推送到远程仓库git push -f：

bash 复制代码

git push -f

注：如果是保护分支，需要先解除保护，推送成功之后再加保护！

由于没有及时回退，导致开发组内其他同事代码更新到了之前的变更，这时候该同事执行git pull会报错：

bash 复制代码

s glt pull
hint: Pulling without specifying how to reconcile divergent branches is
hint: discouraged. You can squelch this message by running one of the following
hint: commands sometime before your next pull:
hint:
hint:    git config pull.rebase false  # merge (the default'strategy)
hint:    git config pull.rebase true   # rebase
hint:    git config pull.ff only       # fast-forward only
hint:
hint: You can replace "git config" with "git config --global" to set a default
hint: preference for all repositories, You can also pass --rebase, --no-rebase
hint: or --ff-only on the command line to override the configured default per
hint: invocation.
Already up to date.

bash 复制代码

$ git status
on brancn dev
Your branch is ahead of 'origin/dev' by l commit.
(use "git push" to publish your local commits)

注意保存好开发变更的代码

将该变更撤销即可：

bash 复制代码

git reset --hard HEAD^
