无法获取MSBuild社区任务RegexReplace工作 [英] Can't get MSBuild Community Task RegexReplace to work

问题描述

我试图复制一组名称以前缀 DR __ 开头的文件，但是副本必须删除该前缀。也就是说， DR__foo 必须复制为 foo 。我尝试这个，这是在文档（.chm）中提供的示例：

I'm trying to copy a bunch of files whose names begin with the prefix DR__, but the copies must have that prefix removed. That is, DR__foo must be copied as foo. I'm trying this, which is based in the example provided in the documentation (the .chm):

<Target Name="CopyAuxiliaryFiles">
    <MakeDir Directories="$(TargetDir)Parameters" Condition="!Exists('$(TargetDir)Parameters')" />
    <ItemGroup>
      <ContextVisionParameterFiles Include="$(SolutionDir)CVParameters\DR__*" />
    </ItemGroup>
    <Message Text="Files to copy and rename: @(ContextVisionParameterFiles)"/>
    <RegexReplace Input="@(ContextVisionParametersFiles)" Expression="DR__" Replacement="">
      <Output ItemName ="DestinationFullPath" TaskParameter="Output" />
    </RegexReplace>
    <Message Text="Renamed Files: @(DestinationFullPath)"/>
    <Copy SourceFiles="@(ContextVisionParameterFiles)" DestinationFiles="@(DestinationFullPath)" />
  </Target>

DestinationFullPath 我看到当我显示它与消息）。因此，复制失败，因为未指定 DestinationFiles 。这里有什么问题？

DestinationFullPath comes out empty (or that's what I see when I display it with Message). Thus, Copy fails because no DestinationFiles are specified. What's wrong here?

编辑：ContextVisionParameterFiles不为空，它包含：

Edit: ContextVisionParameterFiles is not empty, it contains this:

D：\SVN.DRA.WorkingCopy\CVParameters\DR__big_bone.alut; D：\SVN.DRA.WorkingCopy\CVParameters\DR__big_medium.gop

它们实际上是40个文件，但为了清晰起见，我将其修剪了

They're actually 40 files, but I trimmed it for the sake of clarity

推荐答案

收到！它似乎是一个愚蠢的错误和一个看似强制的参数的组合。至于第一个，有两个目标称为 CopyAuxiliaryFiles 。至于第二个，似乎需要 Count 参数。

Got it! It seems to have been the combination of a stupid error and a seemingly compulsory parameter. As for the first one, there were two Targets called CopyAuxiliaryFiles. As for the second one, it seems the Count parameter is needed.

最终的工作版本：

<Target Name="CopyCvParameters">
    <ItemGroup>
      <CvParamFiles Include="$(SolutionDir)CVParameters\DR__*" />
    </ItemGroup>
    <Message Text="Input:&#xA;@(CvParamFiles, '&#xA;')"/>
    <!-- Replaces first occurance of "foo." with empty string-->
    <RegexReplace Input="@(CvParamFiles)" Expression="^.*DR__" Replacement="$(TargetDir)Parameters\" Count="1">
      <Output ItemName ="RenamedCvParamFiles" TaskParameter="Output" />
    </RegexReplace>
    <Message Text="&#xA;Output RenamedCvParamFiles:&#xA;@(RenamedCvParamFiles, '&#xA;')" />
    <Copy SourceFiles="@(CvParamFiles)" DestinationFiles="@(RenamedCvParamFiles)" SkipUnchangedFiles="True" />
  </Target>

请注意：

• 我重命名了目标来解决名称冲突（为什么Visual Studio没有检测到这是一个错误？）


• 我打印的ItemGroups与 @（CvParamFiles，'&＃xA;'）语法，似乎替换; $ b
• 我的regex取代了绝对路径和前缀


• Count =1现在传递给RegexReplace
• 
  

• I renamed the Target to solve the name collision (Why doesn't Visual Studio detect this as an error?)
• I pretty-printed the ItemGroups with the @(CvParamFiles, '
') syntax, which seems to replace ; with line breaks
• My regex replaces the absolute path and the prefix
• Count="1" is now passed to RegexReplace
