To keep a specific file different between two branches during a GitLab merge request, you can use the following steps:
On both branches, make the necessary changes to the file you want to keep different.
Create a new branch from one of the branches that contains the modified file.
Merge the other branch into the new branch using the
--no-commit
option to avoid committing the changes.
git checkout -b new_branch <branch_that_contains_modified_file>
git merge --no-commit <other_branch>
Resolve any conflicts that arise during the merge.
Use
git checkout --theirs
andgit checkout --ours
commands to choose which version of the modified file to keep.Commit the changes and push the new branch to GitLab.
Open a merge request on GitLab and select the new branch as the source branch and the target branch as the destination branch.
In the merge request page, uncheck the box for the modified file under “Changes” to keep it different between the two branches.
Complete the merge request and verify that the file is different between the two branches.
Note: It is recommended to only use this approach for specific cases where keeping a file different between branches is necessary. In most cases, it is better to keep all files consistent between branches to maintain code quality and ensure consistency.
