Azure Pipelines - Reading Template Branch name - Stack Overflow

文章数量:1393850

I am working with Azure Pipelines. We are using a set of templates for different applications where each references a template. Part of the pipeline template includes updating updating work items with references. This works fine but when testing changes to the template files I have been unable to implement any kind of checks for whether the template used is from the main branch or not. Anybody know how to access the specific branch when it is set through resources in the devops UI?

All the obvious answers such as:

• pwsh:

  # Print information about the triggering source
  Write-Host "Triggering Repository: $env:BUILD_REPOSITORY_NAME"
  Write-Host "Triggering Branch: $env:BUILD_SOURCEBRANCH"
  Write-Host "Commit ID: $env:BUILD_SOURCEVERSION"
  

simply return info on the parent repository where the pipeline runs, I am interested in similar "commands"/approaches but for the template repository instead.

When you add a reference to a repository, there are a set of properties available on the resources object that you can use:

resources.repositories.<Alias>.name
resources.repositories.<Alias>.ref
resources.repositories.<Alias>.type
resources.repositories.<Alias>.id
resources.repositories.<Alias>.url
resources.repositories.<Alias>.version

You can access those properties using a runtime expression $[ <exp> ]

trigger: none

resources:
  repositories:
  - repository: templates # alias
    type: git
    name: Temp # projectName/repositoryName or just repositoryName
    ref: main # optional

variables:
  templateName: $[ resources.repositories.templates.name ]
  templateRef: $[ resources.repositories.templates.ref ]
  templateId: $[ resources.repositories.templates.id ]
  templateVersion: $[ resources.repositories.templates.version ]

steps:
- pwsh: |
    write-host "name: $(templateName)"
    write-host "ref: $(templateRef)"
    write-host "id: $(templateId)"
    write-host "version: $(templateVersion)"
  displayName: "show details about template repository"

Which produces the following output:
