如何获得msbuild任务对文件集合进行配置转换? [英] How do I get an msbuild task to do config transforms on a collection of files?

问题描述

我正在尝试转换我拥有的项目中的所有web.config文件，这是我的树状结构:

I am trying to transform all of the web.config files in a project I have, here's a my tree structure:

• Transform.bat
• 转换
  • ConfigTransform.proj
  • Web.Transform.config
  • Transform.bat
  • Transforms
    • ConfigTransform.proj
    • Web.Transform.config
    • web.config
    • 观看次数
      • web.config
      • web.config
      • Views
        • web.config

        还有更多的web.config文件，但想法是，这将找到所有文件并对其应用相同的配置转换.

        There's more web.config files, but the idea is that this will find all of them and apply the same config transform on them.

        我从发现的博客帖子中得到了一些提示，但我陷入了困境最后一步，实际的改造.此外，中间还有一个我不太喜欢的粗糙部分(我不太了解自己在做什么，显然我做错了).这是我到目前为止的位置:

        I've taken a few hints from a blog post I found but I get stuck in the last step, the actual transformation. Also there's a bit of a rough part in the middle that I don't really like (I don't quite understand what I'm doing and I'm obviously doing it wrong). Here's where I am so far:

        <Project ToolsVersion="4.0" DefaultTargets="Transform" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
            <UsingTask TaskName="TransformXml" AssemblyFile="Tools\Microsoft.Web.Publishing.Tasks.dll"/>
        
            <PropertyGroup>
                <SitePath>..\..\Website</SitePath>
                <WebConfigTransformInputFile>$(SitePath)\Web.config</WebConfigTransformInputFile>
                <WebConfigTransformFile>Web.Transform.config</WebConfigTransformFile>
                <OutDir>..\N\N\</OutDir>
        
            </PropertyGroup>
        
            <ItemGroup>
                <_FilesToTransform Include="$(SitePath)\**\web.config"/>
            </ItemGroup>
        
            <Target Name="Transform">
        
            <MakeDir Directories="@(_FilesToTransform->'$(OutDir)%(RelativeDir)')" />
        
            <TransformXml Source="@(_FilesToTransform->'$(OutDir)%(RelativeDir)%(Filename)%(Extension)')"
                          Transform="$(WebConfigTransformFile)"
                          Destination="@(_FilesToTransform->'$(OutDir)%(RelativeDir)%(Filename)%(Extension)')" />
            </Target>
        </Project>
        

        我的Transform.bat看起来像这样:

        My Transform.bat looks like this:

        %systemroot%\Microsoft.NET\Framework\v4.0.30319\MSBuild.exe %CD%\Transforms\ConfigTransform.proj
        

        因此，当我调用批处理时，将创建适当的目录.但是，如您所见，我必须对OutDir有所创造，使其成为.. \ N \ N.由于某些原因，如果我不这样做，OutDir路径将与输入目录完全相同.因此，显然我需要在MakeDir中进行一些更改，但不确定如何.

        So when I call the batch, the appropriate directories get created. However, as you can see I've had to be a little creative with the OutDir, making it ..\N\N. For some reason, if I don't do this the OutDir path will be exactly the same as the input directory. So I obviously need to change something in MakeDir but I'm not sure what.

        真正的问题出在开始进行转换时.我试图保持TransformXml Source参数像这样或这样:

        The real problem comes when it starts to do the transforms. I've tried to keep the TransformXml Source parameter like this or like so:

        @(_FilesToTransformNotAppConfig->'%(FullPath)')
        

        后者给我一个错误无法打开源文件:不支持给定路径的格式."前者给我这样的输出:

        The latter gives me an error "Could not open Source file: The given path's format is not supported." and the former gives me this output:

        Build started 30-4-2012 14:02:48.
        Project "D:\Dev\transform\DoTransforms\Transforms\ConfigTransform.proj" on node 1 (default targets).
        Transform:
          Creating directory "..\N\N\..\..\Website\Views\".
          Transforming Source File: ..\N\N\..\..\Website\Views\Web.config;..\N\N\..\..\Website\Web.config
        D:\Dev\transform\DoTransforms\Transforms\ConfigTransform.proj(32,2): error : Could not open Source file: Could not find a part of the path 'D:\Dev\transform\DoTransforms\Website\Views\Web.config;\Website\Web.config'.
          Transformation failed
        Done Building Project "D:\Dev\transform\DoTransforms\Transforms\ConfigTransform.proj" (default targets) -- FAILED.
        
        Build FAILED.
        

        总结我的问题:

        1. 如何避免OutDir出现路径问题?我摆弄了多条路径，但我做错了.
        2. 如何使TransformXml任务在Source属性中接受多个文件?

        推荐答案

        我认为您已经很接近了.我在下面粘贴了一个示例，该示例显示了如何执行此操作.

        I think you were pretty close. I have pasted a sample below which shows how to do this.

        在我的示例中，我发现位于web.config文件本身旁边的转换.对于您的方案，您可以只使用指向特定文件的MSBuild属性.

        In my sample I discover the transform sitting next to the web.config file itself. For your scenario you can just use an MSBuild property pointing to a specific file.

        <?xml version="1.0" encoding="utf-8"?>
        <Project DefaultTargets="TransformAll" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
        
          <UsingTask TaskName="TransformXml" AssemblyFile="$(MSBuildExtensionsPath32)\Microsoft\VisualStudio\v10.0\Web\Microsoft.Web.Publishing.Tasks.dll"/>
        
          <PropertyGroup>
            <Configuration Condition=" '$(Configuration)'=='' ">Release</Configuration>
            <OutputFolder Condition=" '$(OutputFolder)'=='' ">C:\temp\transformed-files\</OutputFolder>
          </PropertyGroup>
        
          <!--
          This target shows how to transform web.config with a specific transform file associated to that specific web.config file.
          -->
          <Target Name="TransformAll">
        
            <!-- discover the files to transform -->
            <ItemGroup>
              <FilesToTransofm Include="$(MSBuildProjectDirectory)\**\web.config"/>
            </ItemGroup>
        
            <!-- Ensure all target directories exist -->
            <MakeDir Directories="@(FilesToTransofm->'$(OutputFolder)%(RecursiveDir)')"/>
        
            <!-- TransformXml only supports single values for source/transform/destination so use %(FilesToTransofm.Identity)
                 to sned only 1 value to it -->
            <TransformXml Source="%(FilesToTransofm.Identity)"
                          Transform="@(FilesToTransofm->'%(RecursiveDir)web.$(Configuration).config')"
                          Destination="@(FilesToTransofm->'$(OutputFolder)%(RecursiveDir)web.config')" />    
          </Target>
        
        </Project>
