给定相对路径时，如何使MSBUILD评估并打印完整路径? [英] How can I get MSBUILD to evaluate and print the full path when given a relative path?

问题描述

如何让MSBuild评估并在<Message />任务中打印给定相对路径的绝对路径?

How can I get MSBuild to evaluate and print in a <Message /> task an absolute path given a relative path?

属性组

<Source_Dir>..\..\..\Public\Server\</Source_Dir>
<Program_Dir>c:\Program Files (x86)\Program\</Program_Dir>

任务

<Message Importance="low" Text="Copying '$(Source_Dir.FullPath)' to '$(Program_Dir)'" />

输出

将''复制到'c:\ Program Files(x86)\ Program \'

Copying '' to 'c:\Program Files (x86)\Program\'

推荐答案

在MSBuild 4.0中，最简单的方法如下:

In MSBuild 4.0, the easiest way is the following:

$([System.IO.Path]::GetFullPath('$(MSBuildThisFileDirectory)\your\path'))

即使将脚本<Import>绑定到另一个脚本中，该方法也有效；该路径是相对于包含上述代码的文件的.

This method works even if the script is <Import>ed into another script; the path is relative to the file containing the above code.

(从 Aaron的答案以及 在MSBuild 3.5中，您可以使用 ConvertToAbsolutePath 任务:

<Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003"
         DefaultTargets="Test"
         ToolsVersion="3.5">
  <PropertyGroup>
    <Source_Dir>..\..\..\Public\Server\</Source_Dir>
    <Program_Dir>c:\Program Files (x86)\Program\</Program_Dir>
  </PropertyGroup>

  <Target Name="Test">
    <ConvertToAbsolutePath Paths="$(Source_Dir)">
      <Output TaskParameter="AbsolutePaths" PropertyName="Source_Dir_Abs"/>
    </ConvertToAbsolutePath>
    <Message Text='Copying "$(Source_Dir_Abs)" to "$(Program_Dir)".' />
  </Target>
</Project>

相关输出:

Project "P:\software\perforce1\main\XxxxxxXxxx\Xxxxx.proj" on node 0 (default targets).
  Copying "P:\software\Public\Server\" to "c:\Program Files (x86)\Program\".

如果您问我，那会有点long，但是可以.这将是相对于原始"项目文件的，因此，如果放置在被<Import> ed的文件中，则不会相对于该文件.

A little long-winded if you ask me, but it works. This will be relative to the "original" project file, so if placed inside a file that gets <Import>ed, this won't be relative to that file.

在MSBuild 2.0中，有一种方法无法解析"..".但是，它的行为就像绝对路径一样:

In MSBuild 2.0, there is an approach which doesn't resolve "..". It does however behave just like an absolute path:

<PropertyGroup>
    <Source_Dir_Abs>$(MSBuildProjectDirectory)\$(Source_Dir)</Source_Dir_Abs>
</PropertyGroup>

$(MSBuildProjectDirectory)保留属性始终是包含此引用的脚本的目录.

The $(MSBuildProjectDirectory) reserved property is always the directory of the script that contains this reference.

这也将相对于原始"项目文件，因此，如果将其放置在已获得<Import> ed的文件中，则不会相对于该文件.

This will also be relative to the "original" project file, so if placed inside a file that gets <Import>ed, this won't be relative to that file.
