Azure DevOps Pipelines：.artifactignore无法过滤build_scripts目录求助

背景 #

通过Azure DevOps Pipelines将PowerShell模块发布到Azure Artifacts，仓库内的build_scripts目录文件无需发布，因此使用了.artifactignore文件。

现状 #

无论如何配置，build_scripts目录下的文件始终被包含在制品中，安装PowerShell模块时该目录文件依然存在。

• 仓库结构：[对应原截图展示的目录结构]
• Pipeline YAML配置：

- main

name: 'PowerShell Module Project'

variables:
  major: 1
  minor: 0
  patch: $(Build.BuildID)
  buildVer: $(major).$(minor).$(Build.BuildID)

pool: DevPool

stages:
- stage: Build

        buildProperties: 'VERSIONHERE=$(buildVer)'
    - task: CopyFiles@2   
      displayName: 'Copy .artifactignore'   
      inputs:     
        SourceFolder: '$(build.sourcesdirectory)'

    steps:
      - task: DownloadPipelineArtifact@2
        inputs:

          artifactName: 'NuGetPackage'
          itemPattern: '**'
          targetPath: '$(Pipeline.Workspace)'
      - task: NuGetCommand@2
        inputs:
          command: 'push'
          packagesToPush: '$(Pipeline.Workspace)/**/*$(buildVer).nupkg'
          nuGetFeedType: 'internal'
          publishVstsFeed: 'MYProjectName/MyPipelineName' 

• .artifactignore文件内容：

build_scripts/**

• 已尝试操作及日志：
  通过CopyFiles@2任务将.artifactignore复制到制品暂存目录，流水线日志显示已识别该文件：

Using .artifactignore file located at: C:\agent\vsts-agent-win-x64-3.232.0\_work\3\a\.artifactignore for globbing
2 files processed.

已补充制品内容截图和Publish Pipeline artifacts阶段的完整日志，请求排查问题所在。
