我试图通过变量与作业之间的阶段是使用模板在蔚蓝色管道，尝试了很多方法，但仍然没有设法实现它。
我的工作是检查一些东西，并创建vso task.variable，这些变量我要传递到下一阶段

蓝色管道.yaml

stages:

  - stage: CheckProjectType
    displayName: Check Project Type
    jobs:            
      - template: jobs/checkprojectype.yaml@devops

  - stage: PrintProjectType
    dependsOn: CheckProjectType
    displayName: Print Project Type
    jobs: 
      - template: jobs/buildproject.yaml@devops
        parameters:
          outputval: $[ stagedependencies.CheckProjectType.outputs['SetValueStep.projecttype'] ]

检查项目类型.yaml

jobs:
- job: CheckProjectType
  displayName: Check Project Type
  steps:
  - bash: |
      if [ -f *.xml ]; then
        echo "JAVA"
      elif [ -f *.json ]; then
        echo "json file found , Nodejs Project Will Be Built"
        echo "##vso[task.setvariable variable=projecttype;]nodejs"
      elif [ -f *.py ]; then
        echo "Python"
      else
        echo "Not Found"
      fi
    name: itay
    displayName: Checking Current Location

生成项目.yaml

jobs:
- job: BuildProject
  variables:
  - name: myvar123
    value: ${{ parameters.outputval }}
  steps:
  - bash: echo $(myvar123)

我希望得到nodejs，但是我什么也没得到，echo是空的
