Question

我已经进行了自定义web.config转换，我们将其称为CustomTransform，遵循appharbor here上的示例。与示例中的那个一样，我继承自Transform。我还确保导入我的自定义转换：

＆lt; xdt：导入路径=＆＃34;。\ bin \ CustomTransformAssembly.dll＆＃34; namespace =＆＃34; CustomTransformAssembly.Build.Transforms＆＃34; /＆gt;

我可以在此时运行构建，没有任何问题。只有当我尝试使用CustomTransform时才会遇到任何问题。像这样使用转换

＆lt; add name =＆＃34; AConfigElement＆＃34;的connectionString =＆＃34;一个连接字符串＆＃34; XDT：变换=＆＃34; CustomTransform＆＃34; /＆GT;

但是，当我在这个项目上运行msbuild时，我收到以下错误：

错误：无法解决＆＃39; CustomTransform＆＃39;作为一种变换

我应该如何引用CustomTransform以便msbuild找到它？

Answer 1

我正在使用CustomTransformation并且具有完全相同的问题，在我的情况下，我必须覆盖MsBuild的ToolsVersion，/tv:4.0适用于我。

我所拥有的项目已从VS 2008转换为VS 2010，然后转换为VS 2013项目，并在手动编辑.csproj并将项目属性更改为ToolsVersion=12.0后，以某种方式，CustomTransformation开始失败，经过一些跟踪和错误后，我发现它与MsBuild ToolsVersion有关。

开始使用Visual Studio 2019后出现了相同的错误。要解决该错误，我必须：

从.csproj文件中删除一些与转换相关的旧xml
请确保具有自定义转换的引用库引用了相同版本的Microsoft.Web.Xdt（2.1.1）-与当前使用的SlowCheetah相同。首先尝试了绑定重定向，但没有帮助。

已删除的行作为文本：

  <PropertyGroup Label="SlowCheetah">
    <SlowCheetahToolsPath>$([System.IO.Path]::GetFullPath( $(MSBuildProjectDirectory)\..\packages\SlowCheetah.2.5.14\tools\))</SlowCheetahToolsPath>
    <SlowCheetah_EnableImportFromNuGet Condition=" '$(SlowCheetah_EnableImportFromNuGet)'=='' ">true</SlowCheetah_EnableImportFromNuGet>
    <SlowCheetah_NuGetImportPath Condition=" '$(SlowCheetah_NuGetImportPath)'=='' ">$([System.IO.Path]::GetFullPath( $(MSBuildProjectDirectory)\Properties\SlowCheetah\SlowCheetah.Transforms.targets ))</SlowCheetah_NuGetImportPath>
    <SlowCheetahTargets Condition=" '$(SlowCheetah_EnableImportFromNuGet)'=='true' and Exists('$(SlowCheetah_NuGetImportPath)') ">$(SlowCheetah_NuGetImportPath)</SlowCheetahTargets>
  </PropertyGroup>

  <UsingTask TaskName="TransformXml" AssemblyFile="$(MSBuildExtensionsPath32)\Microsoft\VisualStudio\v$(VisualStudioVersion)\Web\Microsoft.Web.Publishing.Tasks.dll" />
  <Target Name="AfterCompile" Condition="Exists('app.$(Configuration).config')">
    <!--Generate transformed app config in the intermediate directory-->
    <TransformXml Source="app.config" Destination="$(IntermediateOutputPath)$(TargetFileName).config" Transform="app.$(Configuration).config" />
    <!--Force build process to use the transformed configuration file from now on.-->
    <ItemGroup>
      <AppConfigWithTargetPath Remove="app.config" />
      <AppConfigWithTargetPath Include="$(IntermediateOutputPath)$(TargetFileName).config">
        <TargetPath>$(TargetFileName).config</TargetPath>
      </AppConfigWithTargetPath>
    </ItemGroup>
  </Target>
  <!--Override After Publish to support ClickOnce AfterPublish. Target replaces the untransformed config file copied to the deployment directory with the transformed one.-->
  <Target Name="AfterPublish">
    <PropertyGroup>
      <DeployedConfig>$(_DeploymentApplicationDir)$(TargetName)$(TargetExt).config$(_DeploymentFileMappingExtension)</DeployedConfig>
    </PropertyGroup>
    <!--Publish copies the untransformed App.config to deployment directory so overwrite it-->
    <Copy Condition="Exists('$(DeployedConfig)')" SourceFiles="$(IntermediateOutputPath)$(TargetFileName).config" DestinationFiles="$(DeployedConfig)" />
  </Target>
  <Import Project="$(SlowCheetahTargets)" Condition="Exists('$(SlowCheetahTargets)')" Label="SlowCheetah" />

由Visual Studio在预览转换时添加）：

  <Target Name="EnsureNuGetPackageBuildImports" BeforeTargets="PrepareForBuild">
    <PropertyGroup>
    ...
    <Error Condition="!Exists('..\packages\Microsoft.VisualStudio.SlowCheetah.3.2.26\build\Microsoft.VisualStudio.SlowCheetah.targets')" Text="$([System.String]::Format('$(ErrorText)', '..\packages\Microsoft.VisualStudio.SlowCheetah.3.2.26\build\Microsoft.VisualStudio.SlowCheetah.targets'))" />
  </Target>


<Import Project="..\packages\Microsoft.VisualStudio.SlowCheetah.3.2.26\build\Microsoft.VisualStudio.SlowCheetah.targets" Condition="Exists('..\packages\Microsoft.VisualStudio.SlowCheetah.3.2.26\build\Microsoft.VisualStudio.SlowCheetah.targets')" />

无法解决＆＃39; CustomTransform＆＃39;作为一种变形
