Question

我们经常发生大量的构建，并且需要大量的资源。因此，我们希望在每次构建后清除构建源和暂存目录。我在本地TFS 2015 Update 1中使用vNext版本。我创建了一个PowerShell脚本作为执行删除的最终任务：

[CmdletBinding()]
param()

begin {
    function Delete-Directory {
        param([string]$directory)

        Write-Output "Attempting to delete '$($directory)'"

        if (Test-Path $directory -pathType container) {
            Get-ChildItem -Path $directory -Force -Recurse | Remove-Item -Recurse -Force
            Write-Output "Successfully deleted the directory: '$($directory)'"
        } else {
            Write-Output "Failed to delete '$($directory)' as it does not exist"
        }
    }
}

process {
    Delete-Directory $env:BUILD_SOURCESDIRECTORY
    Delete-Directory $env:BUILD_STAGINGDIRECTORY
}
end{}

最初，我没有使用Get-ChildItem .... | Remove-Item，而是使用Remove-Item *path* -Recurse -Force，但显然recurse parameter of Remove-Item存在问题。最初它有时是有效的。现在它永远不会起作用。

我尝试了很多不同的变体，这里有一些结果：

使用-Recurse和-Force

Get-ChildItem -Path $directory -Force -Recurse | Remove-Item -Recurse -Force

等于：

Get-ChildItem : Access to the path 'E:\GeneralAgent1\_work\3\s\TfsBuild' is
denied.
At E:\GeneralAgent1\_work\3\s\TfsBuild\Scripts\DeleteSources.ps1:11 char:5
+ Get-ChildItem -Path $directory -Force -Recurse | Remove-Item -Recurse -Force
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo : PermissionDenied: (E:\GeneralAgent1\_work\3\s\TfsBuild:String) [Get-ChildItem], Unauthor
izedAccessException
    + FullyQualifiedErrorId : DirUnauthorizedAccessError,Microsoft.PowerShell.Commands.GetChildItemCommand

否-Recurse

Get-ChildItem -Path $directory -Force -Recurse | Remove-Item -Force

等于：

Remove-Item : Windows PowerShell is in NonInteractive mode. Read and Prompt
functionality is not available.
At E:\GeneralAgent1\_work\3\s\TfsBuild\Scripts\DeleteSources.ps1:11 char:54
+ Get-ChildItem -Path $directory -Force -Recurse | Remove-Item -Force
+ ~~~~~~~~~~~~~~~~~~
    + CategoryInfo : InvalidOperation: (:) [Remove-Item], PSInvalidOperationException
    + FullyQualifiedErrorId : InvalidOperation,Microsoft.PowerShell.Commands.RemoveItemCommand

否-Force

Get-ChildItem -Path $directory -Force -Recurse | Remove-Item -Recurse

返回许多错误，1表示权限被拒绝，而其他错误由于之前被拒绝而未被删除而无法删除：

Remove-Item : Cannot remove item
E:\GeneralAgent1\_work\3\s\Proxies\Development\Isd.Proxies.BO_16.01.1\Avalara\StyleCop.Cache:
You do not have sufficient access rights to perform this operation.
At E:\GeneralAgent1\_work\3\s\TfsBuild\Scripts\DeleteSources.ps1:11 char:54
+ Get-ChildItem -Path $directory -Force -Recurse | Remove-Item -Recurse
+ ~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo : PermissionDenied: (StyleCop.Cache:FileInfo) [Remove-Item], IOException
    + FullyQualifiedErrorId : RemoveFileSystemItemUnAuthorizedAccess,Microsoft.PowerShell.Commands.RemoveItemCommand
......
Lots

否-Recurse或-Force

Get-ChildItem -Path $directory -Force -Recurse | Remove-Item

等于：

Remove-Item : Windows PowerShell is in NonInteractive mode. Read and Prompt
functionality is not available.
At E:\GeneralAgent1\_work\3\s\TfsBuild\Scripts\DeleteSources.ps1:11 char:54
+ Get-ChildItem -Path $directory -Force -Recurse | Remove-Item
+ ~~~~~~~~~~~
    + CategoryInfo : InvalidOperation: (:) [Remove-Item], PSInvalidOperationException
    + FullyQualifiedErrorId : InvalidOperation,Microsoft.PowerShell.Commands.RemoveItemCommand

我还尝试过其他组合并使用Get-ChildItem的参数进行播放，并得到类似的结果。

构建代理帐户具有对根目录的完全权限。

请帮忙吗？

Answer 1

如果你自下而上，你应该可以删除所有内容。在删除项目之前，按降序将Get-ChildItem的结果按其全名排序：

Get-ChildItem -Path $directory -Force -Recurse |
  Sort-Object -Property FullName -Descending |
  Remove-Item -Recurse -Force

Answer 2

不确定这是你的修复，但我的确有点不同

Get-ChildItem $FolderPath | ForEach-Object ($_){
    Remove-Item $_.FullName -Recurse -Force
}

在TFS构建结束时运行时删除项目错误
