Generating T4 on Build using VS 2012

I am trying to generate code on every build of my project using VS2012.

I have 3 projects in my solution :

When I am clicking on Build/Transform All T4 Templates, there is no problem, the generation goes well.

But I am trying to configure my build to include this step automatically on every build.

I have added this code to my csproj :

<Import Project="$MsBuildToolsPath)\Microsoft.CSharp.Targets" />
<PropertyGroup>
   <TransformOnBuild>true</TransformOnBuild>
   <OverWriteReadOnlyOutputFiles>true</OverWriteReadOnlyOutputFiles>
</PropertyGroup>
<Import Project="$(MSBuildExtensionPath32)\Microsoft\VisualStudio\v11.0\TextTemplating\Microsoft.TextTemplating.targets"/>

I have made up myself the path "\Microsoft\VisualStudio\v11.0\TextTemplating\Microsoft.TextTemplating.targets" from what I found on my pc. The example I took it from was :get-visual-studio-to-run-a-t4-template-on-every-build

The problem comes from this line I am using : <#@ include file="$(SolutionDir)\xxx\yyy\zzz\mytemplate.tt">

and I receive the error :

Failed to resolve include text for file : D:\Projects\pppp\qqq\eeee\$(SolutionDir)\xxx\yyy\zzz\mytemplate.tt

As the template works well when it is generated "by hand" (Build/Transform All T4 Templates), I wonder what might be the problem for generating it at build time.

Any idea?

The problem is that when you are running your template during the build process it is being executed under different host and $(SolutionDir) macro does not exist. Try using relative path instead e.g.

<#@ include file="..\xxx\yyy\zzz\mytemplate.tt">
