azure pipeline condition always returns false-CodePudding

I am trying to check if my stage-specific variable sourceCodeChanged is equal to true. If it is true then the stage should be executed, else it should be skipped. I can do this by using a condition and comparing sourceCodeChanged with true. this however is not working for me. what am I doing wrong?

This is a snippet out of my azure-pipelines.yml:

 - stage: build
   dependsOn: determineChanges
   variables:
     sourceCodeChanged: stageDependencies.determineChanges.checkChanges.outputs['check_changes.SOURCE_CODE_CHANGED']
   condition: and(succeeded(), eq(variables.sourceCodeChanged, 'true'))
   jobs:
      - job: buildBinaries
        displayName: Build Binaries
        steps:
          - bash: echo $(sourceCodechanged)
            displayName: TestOutPutDeleteMe #debugging step

I implemented a debugging step called TestOutPutDeleteMe. when the step TestOutPutDeleteMe gets executed it prints out true, so that means the value gets correctly assigned to sourceCodeChanged. If I try to use the variable sourceCodeChanged in the eq() function it always assigns false to the condition and skips all the steps in the stage.

CodePudding user response：

azure pipeline condition always returns false

That because you are using the condition on the stage level. Please try to using following condition:

 - stage: build
   dependsOn: determineChanges
   condition: eq(Dependencies.determineChanges.outputs['checkChanges.check_changes.SOURCE_CODE_CHANGED'], 'true')

Please note that we need update the stages refer from stageDependencies.stageName.jobName.outputs['stepName.variableName'] To Dependencies.stageName.outputs['jobName.stepName.variableName']

And not use the variable for the value Dependencies.determineChanges.outputs['checkChanges.check_changes.SOURCE_CODE_CHANGED']

My test result:

stages:
  - stage: stageA
    jobs:
    - job: A
      pool:
        name: Default
      steps:
      - task: PowerShell@2
        displayName: "create a variable"
        inputs:
          targetType: 'inline'
          script: |
              Write-Host "##vso[task.setvariable variable=CustomVar;isOutput=true]true"                
        name: CustomVariable

  - stage: stageB
    dependsOn: stageA
    condition: eq(Dependencies.stageA.outputs['A.CustomVariable.CustomVar'], 'true')
    jobs:
    - job: A
      pool:
        name: Default
      steps:
      - task: PowerShell@2
        displayName: "output the variable"
        inputs:
          targetType: 'inline'
          script: |
                  Write-Host "hello world"
