I am lots of branches in my repo, now I want to add MR pipeline for the master branch, and enable the Merge checks and Pipelines must succeed optional. unfortunately the repo have so many branches that I don't want to create .gitlab-ci.yml for them one by one. but as I have enabled the options for merge check, MR to the branched are stuck because they are not passed pipeline(no pipeline is configured for the branch).
So anyone can help me out?
