Deployment dependencies condition skipped azure pipeline

Question

I built a pipeline. There are two stages. The deployment stage job has a condition derived from the first stage variable. The sample pipeline is provided below.

pool:
  vmImage: 'ubuntu-latest'

stages:
- stage: Stage
  jobs:
  - deployment: Staging
    displayName: Stage the WebApp
    environment: stg
    strategy:
      runOnce:
        deploy:
          steps:
          - bash: echo "##vso[task.setvariable variable=myStageOutputVar;isOutput=true]true"
            env:
              myVar: 'this is a stage output var'
            name: printvar

- stage: Swap
  dependsOn: Stage
  condition: eq(dependencies.Stage.Staging.outputs['Staging.printvar.myStageOutputVar'], 'true')
  variables:
    myVarfromStage: $[ stageDependencies.Stage.Staging.outputs['Staging.printvar.myStageOutputVar'] ]
  jobs:
  - deployment: Production
    displayName: Swap to production
    environment: adt
    strategy:
      runOnce:
        deploy:
          steps:
          - script: echo $(myVarfromStage)

Every time, the Swap - stage is skipped. Any changes that must be made in the condition?

Answer 1

I suppose you could look up the expression in this document.

You must edit your condition as shown below. Take note of the staging. Staging

- stage: Swap
  dependsOn: Stage1
  condition: eq(dependencies.Stage1.outputs['Staging.Staging.printvar.myStageOutputVar'], 'true')
