Azure DevOps构建Flutter AAB失败：Gradle未生成.aab文件求助

问题核心 #

构建时提示找不到生成的AAB文件，本质是带Flavor的Flutter项目构建后，AAB的输出路径和流水线默认查找路径不一致，且未将生成的文件同步到流水线 artifacts 目录。

修复步骤 #

1. 补充依赖安装步骤 #

在Flutter构建前确保依赖已完整安装，添加flutter pub get步骤：

- task: Hey24sheep.flutter.flutter-command.FlutterCommand@0
  displayName: 'Flutter Pub Get'
  inputs:
    command: 'pub'
    arguments: 'get'
    projectDirectory: '$(PROJECT_DIRECTORY)'

2. 定位并复制AAB文件 #

带Flavor的项目构建后，AAB默认生成路径为$(PROJECT_DIRECTORY)/build/app/outputs/bundle/googlePlayRelease/（其中googlePlay是你的Flavor名称）。添加复制和发布步骤，将文件同步到流水线 artifacts：

- task: CopyFiles@2
  displayName: 'Copy AAB to Artifacts'
  inputs:
    SourceFolder: '$(PROJECT_DIRECTORY)/build/app/outputs/bundle/googlePlayRelease'
    Contents: '*.aab'
    TargetFolder: '$(Build.ArtifactStagingDirectory)'

- task: PublishBuildArtifacts@1
  displayName: 'Publish AAB Artifact'
  inputs:
    PathtoPublish: '$(Build.ArtifactStagingDirectory)'
    ArtifactName: 'AndroidAAB'
    publishLocation: 'Container'

3. 验证Flavor配置一致性 #

确保yaml中buildFlavor: 'googlePlay'与Android项目android/app/build.gradle中的Flavor定义完全一致，示例gradle配置片段：

flavorDimensions "environment"
productFlavors {
    googlePlay {
        dimension "environment"
        // 其他自定义配置
    }
}

完整修改后的YAML #

额外检查点 #

• .gitignore排除build文件夹是正常操作，无需上传到仓库，流水线会在构建时自动生成该目录。
• 若构建仍失败，可在FlutterBuild步骤添加arguments: '--verbose'参数，查看详细日志定位具体错误。
