Question

问题：未根据exclude属性中传递的值正确构建ItemGroups数组。

如果你运行这个脚本它会创建一些示例文件，然后尝试根据Include / Exclude属性创建一个名为TheFiles的数组，问题是当Exclude是硬编码以外的任何东西时，或者是一个非常简单的属性它是错误的。

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

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

非常感谢任何帮助，这让我疯狂。

（注意它的msbuild v4）

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

我已更新上述脚本以使用CreateItem，但是当要排除的项目列表包含多个路径（即 CommonFileExclusion 的值已更改）时仍存在问题：

    <Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003" DefaultTargets="Run">

      <Target Name="Run" >
        <CallTarget Targets="CreateSampleFiles" />
        <CallTarget Targets="DynamicExcludeList" />
        <CallTarget Targets="HardcodedExcludeList" />
      </Target>

      <Target Name="CreateSampleFiles" >
        <MakeDir Directories="AFolder" />
        <WriteLinesToFile Lines="Test" File="AFolder\test.cs" Overwrite="true" />
        <WriteLinesToFile Lines="Test" File="AFolder\test.txt" Overwrite="true" />
        <WriteLinesToFile Lines="Test" File="AFolder\test.vb" Overwrite="true" />
      </Target>

      <Target Name="DynamicExcludeList" >

        <PropertyGroup>
          <CommonFileExclusion>.\DIRECTORY_NAME_TOKEN\**\*.cs;.\DIRECTORY_NAME_TOKEN\**\*.vb;</CommonFileExclusion>
          <FinalExcludes>$(CommonFileExclusion.Replace('DIRECTORY_NAME_TOKEN', 'AFolder'))</FinalExcludes>
        </PropertyGroup>

        <Message Text="FinalExcludes: $(FinalExcludes)" />
        <CreateItem Include=".\AFolder\**\*;"
                     Exclude="$(FinalExcludes)">
          <Output TaskParameter="Include" ItemName="TheFiles"/>
        </CreateItem>
        <Message Text="TheFiles: @(TheFiles)" />

      </Target>

      <Target Name="HardcodedExcludeList" >

        <PropertyGroup>

Answer 1

好的，我尝试了一下，我认为问题来自于您使用表示多个值的SCALAR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>

Answer 2

在目标DynamicExcludeList中使用CreateItem任务代替ItemGroup来动态生成您的项目：

<Target Name="DynamicExcludeList" >

  <PropertyGroup>
    <CommonFileExclusion>.\DIRECTORY_NAME_TOKEN\**\*.cs</CommonFileExclusion>
    <FinalExcludes>$(CommonFileExclusion.Replace('DIRECTORY_NAME_TOKEN', 'AFolder'))</FinalExcludes>
  </PropertyGroup>

  <Message Text="FinalExcludes: $(FinalExcludes)" />

  <CreateItem Include=".\AFolder\**\*;"
              Exclude="$(FinalExcludes)">
    <Output TaskParameter="Include" ItemName="TheFiles"/>
  </CreateItem>

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

从理论上讲，ItemGroup和CreateItem是等价的，但我必须使用CreateItem时遇到过类似情况（动态情况）。
