使用YAML流水线部署Azure Function时遇包找不到错误求助

使用YAML流水线构建并部署Azure Function时，构建与发布阶段运行正常，能生成并下载zip包，但部署阶段持续失败，报错信息：

No package found with specified pattern: D:\a\1\drop\output.zip

已尝试调整环境变量和路径正反斜杠，vmImageName设置为windows-latest，部署阶段输出：

• Downloading: D:\a\1/drop/output.zip
• Error: No package found with specified pattern: D:\a\1\drop\output.zip

构建阶段代码：

- stage: Build
  displayName: Build solution
  jobs:  
  - job: Build
    displayName: Build and publish solution
    pool:
      vmImage: $(vmImageName)
      workspace:
            clean: all
    steps:
    - checkout: self
    - checkout: AzureUtil

    - task: DotNetCoreCLI@2
      displayName: Build and Publish Azure Function
      inputs:
        command: publish
        arguments: '--configuration Release --output publish_output'
        projects: $(projectsPath)/$(projectFileName)
        publishWebProjects: false
        modifyOutputPath: false
        zipAfterPublish: false

    - task: ArchiveFiles@2
      displayName: "Archive files"
      inputs:
        rootFolderOrFile: "$(System.DefaultWorkingDirectory)/publish_output"
        includeRootFolder: false
        replaceExistingArchive: true
        archiveFile: $(Build.ArtifactStagingDirectory)\output.zip'         

    - task: PublishBuildArtifacts@1
      displayName: "Publish build artifacts"
      inputs:
        PathtoPublish: $(Build.ArtifactStagingDirectory)\output.zip'
        artifactName: 'drop'

部署阶段代码：

- stage: Deploy
  displayName: Deploy Azure Function
  dependsOn: Build
  condition: succeeded()
  jobs:
    - deployment: Deploy
      displayName: Deploy Azure Function
      pool:
        vmImage: $(vmImageName)
      environment: 'Web-Dev'
      strategy:
        runOnce:
          deploy:
            steps:
            - task: AzureFunctionApp@1
              displayName: 'Azure functions app deploy'
              inputs:
                azureSubscription: '$(serviceConnectionName)'
                appType: functionApp
                appName: '$(azureFunctionName)'
                package: '$(Pipeline.Workspace)\drop\output.zip' 

你的构建阶段存在语法错误，导致实际发布的构件路径不符合预期：

1. 多余单引号引发路径错误
   在ArchiveFiles@2任务的archiveFile参数，以及PublishBuildArtifacts@1任务的PathtoPublish参数末尾，都多了一个单引号：

   • 错误写法：$(Build.ArtifactStagingDirectory)\output.zip'
   • 正确写法：$(Build.ArtifactStagingDirectory)\output.zip

   这个多余的单引号会让系统生成的zip文件名变成output.zip'（带单引号），但部署阶段寻找的是无单引号的output.zip，因此出现找不到文件的错误。

2. 可选优化：显式添加构件下载任务
   对于deployment类型的作业，建议显式添加构件下载任务，确保构件被正确拉取到部署代理：

   - task: DownloadBuildArtifacts@0
     inputs:
       buildType: 'current'
       downloadType: 'single'
       artifactName: 'drop'
       downloadPath: '$(Pipeline.Workspace)'
   

- task: ArchiveFiles@2
  displayName: "Archive files"
  inputs:
    rootFolderOrFile: "$(System.DefaultWorkingDirectory)/publish_output"
    includeRootFolder: false
    replaceExistingArchive: true
    archiveFile: $(Build.ArtifactStagingDirectory)\output.zip         

- task: PublishBuildArtifacts@1
  displayName: "Publish build artifacts"
  inputs:
    PathtoPublish: $(Build.ArtifactStagingDirectory)\output.zip
    artifactName: 'drop'
