Azure DevOps发布失败：找不到指定模式Zip包求助

我尝试参考相关方案解决问题但未成功。我的Azure DevOps仓库中有一个ASP.NET Core App Service（Web App），发布构建始终报错：

Error: No package found with specified pattern: D:\a\r1\a***.zip

我是App Services CI领域的新手，不确定YAML或CI构建中是否遗漏了步骤。我的YAML配置如下：

stages:
  - stage: SDL
    jobs:
    - job: SDLTools
      pool:
        name: Azure-Pipelines-EO-Windows2022-Office
      steps:
      - task: ms.vss-governance-buildtask.governance-build-task-component-detection.ComponentGovernanceComponentDetection@0
        condition: |
          and(
            eq(variables['Build.SourceBranchName'], 'main'),
            ne(variables['Build.Reason'], 'PullRequest')
          )
        displayName: 'Component Detection'
      - task: ArchiveFiles@2
        inputs:
          rootFolderOrFile: '$(Build.BinariesDirectory)'
          includeRootFolder: true
          archiveType: 'zip'
          archiveFile: '$(Build.ArtifactStagingDirectory)/$(Build.BuildId).zip'
          replaceExistingArchive: true        
      - task: AzureRmWebAppDeployment@4
        inputs:
          ConnectionType: 'AzureRM'
          azureSubscription: 'Subscription'
          appType: 'webApp'
          WebAppName: 'MyWebAppName'
          package: '$(System.DefaultWorkingDirectory)/*.zip'
      - task: PublishBuildArtifacts@1

我看到归档已完成：

D:\a\_work\_tasks\ArchiveFiles_35346534345f\2.231.0\7zip\7z.exe a -tzip -mx=5 D:\a\_work\1\a\26395403.zip @D:\a\_work\_temp\v6pxdmipzc

但部署时失败，报错：

No package found with specified pattern: D:\a\_work\1\s\*.zip<br/>Check if the package mentioned in the task is published as an artifact in the build or a previous stage and downloaded in the current job

问题原因与修复方案 #

1. 核心问题：路径不匹配 #

你的ArchiveFiles@2任务把Zip包生成在了$(Build.ArtifactStagingDirectory)（对应实际路径D:\a\_work\1\a），但AzureRmWebAppDeployment@4任务指定的package路径是$(System.DefaultWorkingDirectory)/*.zip（对应实际路径D:\a\_work\1\s，即代码目录），两个路径完全不匹配，导致部署任务找不到包。

2. 直接修复步骤 #

修改AzureRmWebAppDeployment@4中的package参数，指向正确的归档路径：

package: '$(Build.ArtifactStagingDirectory)/$(Build.BuildId).zip'

或者用通配符匹配该目录下所有Zip包：

package: '$(Build.ArtifactStagingDirectory)/*.zip'

3. 额外优化建议 #

• 确认$(Build.BinariesDirectory)包含Web App编译输出：如果该目录为空，生成的Zip包也会无效。对于ASP.NET Core项目，建议先添加发布任务：

  - task: DotNetCoreCLI@2
    displayName: '发布Web应用'
    inputs:
      command: 'publish'
      publishWebProjects: true
      arguments: '--configuration $(BuildConfiguration) --output $(Build.BinariesDirectory)'
      zipAfterPublish: false
  

• 完善PublishBuildArtifacts@1任务参数，明确发布的工件信息：

  - task: PublishBuildArtifacts@1
    inputs:
      PathtoPublish: '$(Build.ArtifactStagingDirectory)'
      ArtifactName: 'drop'
      publishLocation: 'Container'
