How to tell if it is the first pipeline for a newly created merge request

Hi there,

Is there a way to determine in the context of a pipeline for a merge request, if there has already been a successful pipeline for that merge request?

I have looked at several of the predefined variables in the GitLab CI but there doesn’t seem to be anything suitable…

As a bit more info on my situation, I have some jobs related to the UI of my app and some jobs related to the Backend of my app. I am using rules:changes to only run either UI or Backend jobs depending on what files have changed in a commit. This works great, however:

What I want to do is for the first time a pipeline is run for a merge request, run the FULL pipeline regardless of what files have changed.

Running using shared runners on GitLab.com and v14.7
