remote: GitLab: You are not allowed to push code to protected branches on this project.
To code.aliyun.com:xxxx/xxx.git
! [remote rejected] master -> master (pre-receive hook declined)
error: failed to push some refs to ‘git@code.aliyun.com:xxxx/xxx.git’
原因： GitLab一些分支默认被保护，仅仅拥有master级别的用户才能提交到保护分支，而且master分支默认是保护分支，其他用户需要通过合并issue请求来提交上去
让同事在阿里code上将我的帐号设置为owner组内后，再次提交，可以完成
