git删除所有提交历史记录

这种方式是最快最有效的

进项目根目录启动git bash，然后执行这些即可

最后的 git push -f origin master 会失败，直接在idea里push就能成功了

.Checkout

   git checkout --orphan latest_branch

. Add all the files

   git add -A

. Commit the changes

   git commit -am "commit message"

. Delete the branch

   git branch -D master

.Rename the current branch to master

   git branch -m master

.Finally, force update your repository

   git push -f origin master
