How to trigger azure pipeline in one topic branch during push for another topic branch

Question

My azure devops pipileine's yaml file is not in master branch of bitbucket. Its in another branch inside master branch (master/pipeline-branch). I am trying to trigger that build when there is a push to another topic branch which is also not the master branch. (master/topic/secondary).

In my yaml file I have written the trigger like this.

trigger: - topic/secondary

But no build is triggered when I push a file to secondary branch.

Answer 1

you need to cherry pick\merge commits with this file to the secondary branch or just commit the yaml file to the secondary branch. when a commit is made a decision to start the build or not is being made by evaluating the yaml file inside the branch a commit was made to. if the file doesnt exist in that branch - there is nothing to trigger
