@yuanboliu, I understand that this is a relatively long feature development. Can you develop on the branch first, and then merge it into the master after completion? If a complete output cannot be formed, the version may not be released for this reason

I found that this issue includes many contents. I have a problem with the operation here: the realization of this part of the requirement should be submitted to the corresponding branch first, and then merged into the master after the realization and verification are completed, or it will affect to the release of the master.

@yuanboliu, can I delete this module first, and after the branch is built, you merges it into the branch again?

ok, go ahead, I've saved it in local environment
