使用msbuild删除文件夹和文件时出现问题

Question

我正在尝试使用msbuild删除一些文件和文件夹，不包括少量文件。

<PropertyGroup>
    <SolutionName>TestProject</SolutionName>
    <SolutionFileName>$(MSBuildProjectDirectory)/$(SolutionName).sln</SolutionFileName>
    <Configuration Condition=" '$(Configuration)' == '' ">Release</Configuration>
    <BuildVersion Condition="'$(BuildVersion)' == ''">1.0.0.0</BuildVersion>      <BuildTargetFolder>$(MSBuildProjectDirectory)\..\..\TestProjectBuild</BuildTargetFolder>
    <OutputPath>$(BuildTargetFolder)\Builds\$(Configuration)\TestProject - $(BuildVersion)</OutputPath>    
  </PropertyGroup>

<Target Name="CleanDirExludeFinalOutput">
    <ItemGroup>
      <!-- Item to get all files recursively in the DeleteRoot folder -->
      <FilesToDelete Include="$(OutputPath)\**\*.*" Exclude="$(OutputPath)\**\*.msi;$(OutputPath)\**\*.exe"/>
      <!-- Item to get all folders from the files to be deleted -->
      <FoldersToDelete Include="%(FilesToDelete.RootDir)%(FilesToDelete.Directory)" Exclude="$(OutputPath)"/>
    </ItemGroup>
    <!-- Display what will be deleted -->
    <Message Text=" # @(FilesToDelete)" Importance="high" />
    <Message Text=" # @(FoldersToDelete)" Importance="high" />

    <!-- Delete the files -->
    <Delete Files="@(FilesToDelete)" Condition=" $(OutputPath)!=''" ContinueOnError="true"/>
    <!-- Remove the folders -->
    <RemoveDir Directories="@(FoldersToDelete)" Condition="$(OutputPath)!=''" />
  </Target>

现在，当我尝试使用VisualStudio2010 CommandPrompt中的msbuild命令运行上述脚本时，我看到所有文件都被删除了。我不想删除TestProject.msi，setup.exe。

如果我设置

，上面的工作正常

<BuildTargetFolder>C:\temp\TestProjectBuild</BuildTargetFolder>

除TestProject.msi，setup.exe

外，所有文件和文件夹都被删除

有人可以帮我解决这个问题吗？
