无法从github操作中的不同步骤读取变量

我想读一个变量 value_deploy_path 从另一个步骤,但它只是不打印任何内容。

name: CICD_develop
on:
  push:
    branches:
      - "*"

jobs:

  SETVARS:

    runs-on: 'windows-latest'

    steps:

      - name: Get env data from web.SetParameters.xml

        id: retrivevalue

        env:
          STORE_SERVER: ${{ env.storeserver }}

        run: |

          $xmlPath = "\\$env:STORE_SERVER\D$\Jenkins\Inventory\web.Set.xml"

          $key_deploy_path = "deploy_path"

          $value_deploy_path = (Select-Xml -Literalpath $xmlPath -XPath "//setParameter[@name='$key_deploy_path']").Node.Value
          Write-Host "The value for key '$key_deploy_path' is $value_deploy_path"
          echo "##vso[task.setvariable variable=value_deploy_path;isOutput=true]$value_deploy_path"    #Set output variable
          echo "Within: ${{ steps.retrivevalue.outputs.value_deploy_path }}"

      - name: print one myvalue_deploy_path from web.SetParamters.xml

        run: |
          echo "${{ steps.retrivevalue.outputs.value_deploy_path }}"
         

      - name: print myvalue_deploy_path from web.SetParamters.xml
        run: |
          $rvalue = ${{ steps.retrivevalue.outputs.value_deploy_path }}
          Write-Host "The retrived value is: $rvalue"

输出

The value for key '$key_deploy_path' is D:\\myfolder

Within:


The retrived value is:

不幸的是,除了 Write-Host "The value for key '$key_deploy_path' is $value_deploy_path" I.E D:\\myfolder

你能告诉我为什么以及如何获得的价值吗 value_deploy_path 采取不同的步骤?
