Rebase hotfixes

[ciltocruz]

Hello.

I have a problem and I want to ask if there is any way to solve it. It is not a bug of the plugin. it works quite well, but I have found a casuistry in which it has caused an error. I don't know if I haven't configured it correctly.

I've made a feature (feat 1) and merged it into my develop branch. This feature is in the testing phase. Suddenly a hotfix appears in production (main).

The hotfix is pushed to main directly (hotfix/someName --> main).

When doing "rebase" from main to develop, the problem appears indicating that there are previous commits (feat 1) and that I must pull.

Can I solve it with this plugin or do I have to rebase the hotfixes manually?

Hi @ciltocruz,

this plugin is mainly a hacky way to achieve simple backmerges with semantic-release.
So far, hotfixes have not been part of the scope. There's also a note in the readme about this:

Especially automatic hotfix releases may not be possible as those usually lead to merge conflicts with develop that have to be resolved manually. In such cases the release workflow will fail, causing a red pipeline!

But merge conflicts are not your issue.
You're rebasing develop onto main, so commits in develop but not in master will get a new commit hash.
You'd need to push that develop branch with -f for the push to get through; however this would also wipe other changes on the develop branch that are pushed during pipeline run.

Can you try to use backmergeStrategy: merge instead?

Hello @saitho
I tried. Unsuccessfully.

What I am doing now is that when this happens, then the pipeline fails but only because of the update of the develop branch on main. So what I do is do it manually.

Thanks!
