Execute task when build is cancelled - Azure DevOps Pipelines

Question

I need my pipeline to run a task if the build is cancelled either by a user or automatically (by the system itself).

Is there any condition to do so?

Thanks!

Answer 1

Yes, you can use always()

steps:
- script: echo I did a thing
  condition: and(always(), eq(someConditionHere))

More on that here: https://learn.microsoft.com/en-us/azure/devops/pipelines/process/conditions?view=azure-devops&tabs=yaml

Answer 2

If you need the task to run only when the build is canceled, you need to check both always() and succeededOrFailed().

Because succeededOrFailed() is false when the pipeline is canceled, the following condition works:

- script: |
    echo "Pipeline was canceled."
  condition: and(always(), eq(succeededOrFailed(), false))
