1.切换分支
git checkout -b dev origin/feature/迭代1.1
2.提交本地代码到github
git init //初始化git
git config --global core.autocrlf false //解决：warning: LF will be replaced by CRLF
git add . //添加到缓存
git commit -m "first commit" //提交代码
git remote add origin git@github.com:xxxxx/xxxxx.git //关联到git
git push -u origin master -f //使用-f 强制push
