如何从多个项目构建单个Azure DevOps工件并解决语法问题

核心语法修正：projects参数的正确写法 #

你之前的projects参数用逗号分隔多个字符串不符合YAML语法规范，正确写法是使用YAML数组格式，每个项目路径单独一行并以-开头，也可以用方括号包裹的单行数组。

方案1：合并所有项目输出为目录形式的工件 #

该方案将所有项目的发布文件直接合并到同一个目录，最终工件是包含所有文件的目录：

steps:
- task: DotNetCoreCLI@2
  displayName: 'Build Front-End'
  inputs:
    command: 'build'
    projects:
      - '**/FirstUIProject.csproj'
      - '**/SecondUIProject.csproj'
      - '**/NthUIProject.csproj'
    arguments: '--configuration $(buildConfiguration)'

- task: DotNetCoreCLI@2
  displayName: 'Publish Front-End Projects'
  inputs:
    command: 'publish'
    publishWebProjects: False
    projects:
      - '**/FirstUIProject.csproj'
      - '**/SecondUIProject.csproj'
      - '**/NthUIProject.csproj'
    arguments: '--configuration $(BuildConfiguration) --output $(Build.ArtifactStagingDirectory)/UI'
    zipAfterPublish: False # 关闭单个项目自动打包，让所有文件合并到UI目录

- task: PublishBuildArtifacts@1
  displayName: 'Publishing UI Artifact'
  inputs:
    pathtoPublish: '$(Build.ArtifactStagingDirectory)/UI'
    artifactName: 'UI Build Artifact'

方案2：合并所有项目输出为单个ZIP包 #

如果需要把所有内容打包成单个ZIP文件作为工件，可添加ArchiveFiles任务：

steps:
- task: DotNetCoreCLI@2
  displayName: 'Build Front-End'
  inputs:
    command: 'build'
    projects:
      - '**/FirstUIProject.csproj'
      - '**/SecondUIProject.csproj'
      - '**/NthUIProject.csproj'
    arguments: '--configuration $(buildConfiguration)'

- task: DotNetCoreCLI@2
  displayName: 'Publish Front-End Projects'
  inputs:
    command: 'publish'
    publishWebProjects: False
    projects:
      - '**/FirstUIProject.csproj'
      - '**/SecondUIProject.csproj'
      - '**/NthUIProject.csproj'
    arguments: '--configuration $(BuildConfiguration) --output $(Build.ArtifactStagingDirectory)/UI'
    zipAfterPublish: False # 关闭单个项目打包，先合并文件到统一目录

- task: ArchiveFiles@2
  displayName: 'Combine UI Output into Single ZIP'
  inputs:
    rootFolderOrFile: '$(Build.ArtifactStagingDirectory)/UI'
    includeRootFolder: False
    archiveType: 'zip'
    archiveFile: '$(Build.ArtifactStagingDirectory)/UI_Combined.zip'
    replaceExistingArchive: True

- task: PublishBuildArtifacts@1
  displayName: 'Publishing UI Artifact'
  inputs:
    pathtoPublish: '$(Build.ArtifactStagingDirectory)/UI_Combined.zip'
    artifactName: 'UI Build Artifact'

关键说明 #

• zipAfterPublish: False：禁用单个项目自动打包ZIP的功能，确保所有项目的输出文件直接合并到指定的UI目录中。如果保留zipAfterPublish: True，每个项目会生成单独的ZIP包，最终工件目录会包含多个独立ZIP文件。
• 数组格式的projects参数：YAML会正确识别多个项目路径，任务会依次处理每个项目。
