MSBuild ItemGroup包含/排除模式问题 [英] MSBuild ItemGroup Include/Exclude pattern issue

问题描述

问题:无法根据排除属性中传递的值正确构建ItemGroups数组.

Problem: an ItemGroups array isn't correctly build based on the value passed in the exclude attribute.

如果运行此脚本，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不是硬编码或非常简单的属性时，它就会出错.

If you run this scrip it creates some sample file then tries to create an array called TheFiles based on the Include/Exclude attributes, problem is when the Exclude is anything other than hardcoded or a very simple property it gets it wrong.

目标DynamicExcludeList错误地选择了以下文件:
.\ AFolder \ test.cs;.\ AFolder \ test.txt

The target DynamicExcludeList's incorrectly selects these files:
.\AFolder\test.cs;.\AFolder\test.txt

目标HardcodedExcludeList正确选择了以下文件:
.\ AFolder \ test.txt

The target HardcodedExcludeList's correctly selects these files:
.\AFolder\test.txt

非常感谢您的帮助，这真让我发疯.

这是输出，请注意"TheFiles"和"TheFilesWithHardcodedExcludes"之间的区别

This is the output, note the differences between 'TheFiles' and 'TheFilesWithHardcodedExcludes'

编辑

我已经更新了上面的脚本以使用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，仍然存在问题:

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):

推荐答案

好吧，我尝试了一下，我认为问题出在您使用代表多个值的SCALAR值的属性这一事实.我建议进行批处理和转换(请参见 http://scottlaw.knot.org/blog/?p = 402 和 http://msdn.microsoft.com/zh-我们/library/ms171476.aspx ).例如，以下代码正在工作:

Ok, I tried a little and I think the problem comes from the fact that you use a property which represent SCALAR value for multiple values. I would recommend batching and transforming (see http://scottlaw.knot.org/blog/?p=402 and http://msdn.microsoft.com/en-us/library/ms171476.aspx). For example the following code is working :

<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>
