将 output 传递给 azure 发布管道中的新作业

Question

I am looking for some help passing the output from a powershell script into another task in a release pipeline.

The workflow is as follows:

I need to pass a variable that is created from the powershell script into the Manual intervention text message.

In a yaml pipeline, I would use

  Write-Host "##vso[task.setvariable variable=myvar;isOutput=true]foo"

however in order to access this it only works if the previous task was a dependant, which I do not believe you can do in a release pipeline.

I don't think that's true. In YAML pipelines, you can set variables at the root, stage, and job level. You can also use a variable group to make variables available across multiple pipelines. Some tasks define output variables, which you can consume in downstream steps, jobs, and stages .

Coming to YAML, you can access variables across jobs and stages by using dependencies . By default, each stage in a pipeline depends on the one just before it in the YAML file. If you need to refer to a stage that isn't immediately prior to the current one, you can override this automatic default by adding a dependsOn section to the stage.

For example, let's assume we have a task called MyTask , which sets an output variable called MyVar . To use outputs in a different job:

jobs:
 - job: A
  steps:
  # assume that MyTask generates an output variable called "MyVar"
  # (you would learn that from the task's documentation)
 - task: MyTask@1
    name: ProduceVar  # because we're going to depend on it, we need to name the step
 - job: B
  dependsOn: A
  variables:
    # map the output variable from A into this job
    varFromA: $[ dependencies.A.outputs['ProduceVar.MyVar'] ]
  steps:
 - script: echo $(varFromA) # this step uses the mapped-in variable
