以下方法是在當前的分支下新建一個分支，然后把之前分支刪除，接着把新建的分支重命名為原分支名稱，最后把分支強制推送到遠程
1.Checkout git checkout --orphan latest_branch 2. Add all the files git add -A 3. Commit the changes git commit -am "commit message" 4. Delete the branch git branch -D master 5.Rename the current branch to master git branch -m master 6.Finally, force update your repository git push -f origin master
