Azure devops 根据触发器分支设置YAML变量

我试图了解在devops中定义构建管道的yaml语法

我想根据触发构建的分支在文件中设置变量

# trigger:
 batch: true
 branches:
   include:
    - master
    - develop
    - staging

 variables:
    buildConfiguration: 'Release' # Can I set this according to the branch which triggered the build?

我尝试了以下方法，但似乎无法定义变量两次

 variables:
  solution: '**/*.sln'
  buildPlatform: 'Any CPU'

 variables:
  condition: eq(variables['Build.SourceBranch'], 'refs/heads/develop')
  buildConfiguration: 'Develop'

 variables:
  condition: eq(variables['Build.SourceBranch'], 'refs/heads/release')
  buildConfiguration: 'Release'

---

感谢您的帮助：-）

我可能会添加一个脚本步骤来计算这些。因此，创建某种脚本来检查$（Build.SourceBranch）的值，并像通常那样设置

buildConfiguration

的值：

echo '##vso[task.setvariable variable=buildConfiguration]something'

---

如果有人感兴趣的话，我就这样结束了

 trigger:
  batch: true
  branches:
   include:
    - master
    - develop

      Write-Host "##vso[task.setvariable variable=buildConfiguration;]Release"
    }
    If ("$(Build.SourceBranch)" -eq "refs/heads/develop") {
      Write-Host "##vso[task.setvariable variable=buildConfiguration;]Debug"
    }
 - script: | 
    echo building configuration $(buildConfiguration)

 - task: VSBuild@1
   inputs:
    solution: '$(solution)'
    msbuildArgs: '/p:DeployOnBuild=true /p:WebPublishMethod=Package /p:PackageAsSingleFile=true /p:SkipInvalidConfigurations=true /p:PackageLocation="$(build.artifactStagingDirectory)"'
    platform: '$(buildPlatform)'
    configuration: '$(buildConfiguration)'
    clean: true
    vsVersion: '15.0'

非常感谢。我还没见过这些。阅读时间。只需查看azure devops的

variables

文章，它提供了关于这些变量的信息。基本上你所要做的就是回显一个看起来像那样的字符串谢谢。我在设置多个YAML文件时偶然发现了这一点。。。但它似乎有点笨重，所以我将尝试使用变量。这个pwsh到底在哪里？这是完整的文件。它位于我的项目根目录中的azure-pipelines.yml中
