MSBuild ItemGroup 包含/排除模式问题

Question

问题:未根据排除属性中传递的值正确构建 ItemGroups 数组。

如果您运行此脚本，它会创建一些示例文件，然后尝试根据包含/排除属性创建一个名为 TheFiles 的数组，问题是当排除不是硬编码或非常简单的属性时，它会出错。

目标 DynamicExcludeList 错误地选择了这些文件:
.\AFolder\test.cs;.\AFolder\test.txt

目标 HardcodedExcludeList 正确选择这些文件:
.\AFolder\test.txt

非常感谢任何帮助，这让我发疯。

(注意其 msbuild v4)

          />

        <Message Text="TheFiles: @(TheFiles)" />

        </ItemGroup>
        <Message Text="TheFilesWithHardcodedExcludes: @(TheFilesWithHardcodedExcludes)" />

      </Target>  
    </Project>

这是输出，请注意“TheFiles”和“TheFilesWithHardcodedExcludes”之间的差异

EDITS

I've updated the above script to use the CreateItem, however there is still an issue when the list of items to exclude contains more than 1 path (i.e. the value of CommonFileExclusion has changed):

        <CreateItem Include=".\AFolder\**\*;"

好吧，我尝试了一点，我认为问题来自于您使用一个代表多个值的标量值的属性。我建议批处理和转换(请参阅 http://scottlaw.knot.org/blog/?p=402 和 http://msdn.microsoft.com/en-us/library/ms171476.aspx )。例如，以下代码正在运行:

<Target Name="DynamicExcludeList" >
  <ItemGroup>
    <ExtensionsExcluded Include="cs;vb" />
  </ItemGroup>

  <CreateItem Include=".\AFolder\**\*"
          Exclude="@(ExtensionsExcluded->'.\AFolder\**\*.%(identity)')">
    <Output TaskParameter="Include" ItemName="TheFiles"/>
  </CreateItem>
  <Message Text="TheFiles: @(TheFiles)" />
</Target>
