I have a multi stage pipeline that has a trigger from another pipeline. If the triggering pipeline is not in the “main” branch I want to skip all prod stages, for example:

  - ${{ if value: eq(variables.resources.pipeline.ACP_Server_Build.sourceBranch, 'refs/heads/main') }}:
    - stage:....

Is there a way to use the resource sourceBranch in a condition as I described?

If I were using the target pipeline source branch I could do it with the following:

variables:
  - name: isMain
    value: ${{ eq(parameters.branch, 'main') }}

  - ${{ if eq(variables['isMain'], true) }}:
    - stage:....

However the documentation shows that the variable: resources.pipeline.resourceName.sourceBranch is not available as a template variable. If I try to set a variable like this:

  - name: resourceBranch
    value: $(resources.pipeline.resourceName.sourceBranch)

Then $(resourceBranch) is available inside a step but also doesn’t work in a template condition. I don’t really want to add a condition: to each stage because unlike the root level condition, which simply leaves the skipped stages out of the run, adding the condition on each stage individually results in a lot of “Stage Skipped” items in the deployment.
