Azure Release Pipeline未清理代理Package文件夹问题求助

下面提供几种强制清理相关目录的方案，按需选择：

方案1：清理IIS站点的物理目录 #

在停止站点后、部署前，用PowerShell任务清空目标站点的物理文件夹：

• 在StopIIS任务之后、DeployIIS任务之前添加以下PowerShell任务：

# 替换成你的IIS站点实际物理路径，比如C:\inetpub\wwwroot\MyAspNetApp
$targetPath = "C:\inetpub\wwwroot\${{ variables.IISWebsiteName }}"
if (Test-Path $targetPath) {
    # 递归删除目录下所有内容，-Force处理只读文件
    Remove-Item "$targetPath\*" -Recurse -Force
    Write-Host "已清空目标站点目录: $targetPath"
} else {
    Write-Host "目标目录不存在，跳过清理"
}

方案2：通过部署任务参数自动清理 #

IISWebAppDeploymentOnMachineGroup任务支持通过额外参数禁用默认的“保留服务器额外文件”规则，自动清理站点目录：
在DeployIIS任务的inputs里添加一行：

AdditionalArguments: '-disableRule:SkipExtraFilesOnServer'

默认情况下，这个任务会保留服务器上不属于部署包的文件，添加该参数后会删除这些额外文件，只保留部署包里的内容。

方案3：清理代理上的临时下载目录 #

如果要清理代理机器上的临时下载文件夹（$(Pipeline.Workspace)下的目录），可以在下载构建产物之前或者部署完成后添加脚本任务：

- script: |
    if exist "$(Pipeline.Workspace)\buildPipeline\My Asp Net App" (
        rmdir /s /q "$(Pipeline.Workspace)\buildPipeline\My Asp Net App"
        echo 已清理代理临时下载目录
    ) else (
        echo 代理临时目录不存在，跳过清理
    )
  displayName: '清理代理旧临时目录'
