Tag based on Build Variable

[b-twis]

Hello,

Is it possible to use build variables in the tags. I have tried with the following two YAMl options (I am running a multi stage YAML pipeline).

Where ENV_RELEASE is a custom variable set at runtime and BUILD_REPOSITORY_NAME is a standard one set by the pipeline.

- task: WorkItemUpdater@2
  displayName: 'Tag WorkItems'
  inputs:
    workitemsSource: 'Build'
    workItemType: 'Bug,Feature,Task,User Story'
    linkBuild: true
    updateAssignedTo: 'Never'    
    addTags: |
      ${{ parameters.environment }}
      $(BUILD_REPOSITORY_NAME)
      $(ENV_RELEASE)

Results in the following tags 'cl-uat', '$(BUILD_REPOSITORY_NAME)', '$(ENV_RELEASE)'
THe first tag is correct, but the other two are not.

The following has the same issue.

- task: WorkItemUpdater@2
  displayName: 'Tag WorkItems'
  inputs:
    workitemsSource: 'Build'
    workItemType: 'Bug,Feature,Task,User Story'
    linkBuild: true
    updateAssignedTo: 'Never'    
    addTags: |
      ${{ parameters.environment }}
      $[variables.BUILD.REPOSITORY.NAME]     

Same results as avove .Tags 'cl-uat', '$[variables.BUILD.REPOSITORY.NAME]', '$[variables.ENV_RELEASE]'

Any pointer here would be great.

Thanks,

Basil
