解决Gitlab仓库developer无法push问题

进入settings=>repository=>protected branches里，修改Allowed to push为Developers + Maintainers 或者直接点击Unprotect.

developer权限也可提交代码

master分支下修改了文件，计划push，发现没有权限

remote: GitLab: You are not allowed to push code to protected branches on this project.
! [remote rejected] master -> master (pre-receive hook declined)

修改文件并添加

git add .

git commit -m "m"

git checkout -b update_fastjosn_version  //新建分支

git push  //此处提示错误
git push --set-upstream origin update_fastjson_version  //再次OK了
可以看到push成功了，再登陆gitlab，新建一个merge request就行了，让有merge权限的人merge一下。
