How to only run a pipeline for a PR and not also for the source branch?

Question

I have Pipelines configured to run for all `feature/**` branches and also for PR's.

When I create a PR, 2 pipelines are triggered: one for the PR, one for the source branch.

The reason for my setup is that I want development feedback asap when developing in a `feature/**` branch. Then, once the developer creates as PR, only that pipeline should run (otherwise it's just a waste to run 2 almost identical pipelines).

Any suggestions?

You're right, TIL!

That sounds like a very useful build to run.

Why do you need branch builds then?

Hi Martyn,

I don't think thats exactly the same.

The branch pipeline only tests the code in the branch as it is, whereas the pr pipelines performs a merge into the destination branch and then runs the pipeline. Meaning, it will test the situation that will exist after the merge. Or at least, that is my understanding of it.

Hi George,

I think you can just remove the

pull-requests:
    '**':
      - step: *Build
      # etc

from your pipelines and you will get the desired behaviour.

I hope that helps!
