Preventing MSBuild from building a project in a .sln without using Solution Configurations

I want to inhibit the building of certain projects within a solution from building (within a TeamCity Build Configuration in order to optimize the speed of my Commit Build feedback if you must know).

I'm aware of the Solution Configurations mechanism but don't want to have to force lots of .sln files to end up with ever开发者_如何学运维y permutation of things I want to be able to switch off. I have Convention based rule where I want to say "If I'm doing the Commit Build, I dont want to do the final installer packaging". (And I don't want to break it out into a separate solution).

I'd prefer not to use a solution involving find and replace in the .sln file or in a .proj file created via [MsBuildEmitSolution][1]. I'm aware of questions here which cover the out of the box solution and this slightly related question.

I see MSBuild /v:diag is saying:

 2>Target "Build" in file "Z.sln.metaproj" from project "Z.sln" (entry point):
   Using "MSBuild" task from assembly "Microsoft.Build.Tasks.v4.0, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a".
   Task "MSBuild"
     Global Properties:
       BuildingSolutionFile=true
         CurrentSolutionConfigurationContents=<SolutionConfiguration>
   <ProjectConfiguration Project="{C83D035D-169B-4023-9BEE-1790C9FE22AB}" AbsolutePath="X.csproj" BuildProjectInSolution="True">Debug|AnyCPU</ProjectConfiguration>
   <ProjectConfiguration Project="{15E7887D-F1DB-4D85-8454-E4EF5CBDE6D5}" AbsolutePath="Y.csproj" BuildProjectInSolution="True">Debug|AnyCPU</ProjectConfiguration>
 </SolutionConfiguration>

So the question is:

Is there a neat way of me getting to do an XPath replace or similar to have the effect of changing BuildProjectInSolution="True" to BuildProjectInSolution="False" for Project Y above

Failing that, is there a relatively simple edit I can do within a .ccproj (An Azure 1.4 Package) or a .csproj (a general project) file to cause the effects (including triggering of dependent projects) of the project being enabled within a commandline msbuild Z.sln solution build to be nullified?

Not sure it qualifies as neat, but you can set CustomAfterMicrosoftCommonTargets to import an msbuild file to over-ride the BuildDependsOn property, pointing it to your own custom build task. Basically, by setting CustomAfterMicrosoftCommonTargets you get msbuild to import an msbuild file containing the following:

<PropertyGroup>
    <OldBuildDependsOn>$(BuildDependsOn)</OldBuildDependsOn>
    <BuildDependsOn>MyBuild</BuildDependsOn>
</PropertyGroup>

<Target Name="OldBuild" DependsOnTargets="$(OldBuildDependsOn)" />

<Target Name="MyBuild">
    <CallTarget Targets="OldBuild" Condition="<IfIWantThis>" /> 
</Target>

Edit

You can use the following MyBuild target to Include/Exclude projects based on regular expressions passed in as IncludeInBuild and ExcludeFromBuild properties. (If you want complex regexes, you may fall foul of MSBuild special character escaping, but this works well enough for simple matching)

> msbuild /p:ExcludeFromBuild="Tests|Install|Azure"

<Target Name="MyBuild">
    <CallTarget Targets="OldBuild" Condition="('$(IncludeInBuild)'=='' OR
    '$([System.Text.RegularExpressions.Regex]::IsMatch($(MSBuildProjectFullPath),
    $(IncludeInBuild), 
    System.Text.RegularExpressions.RegexOptions.IgnoreCase))'=='True') AND 
    ('$(ExcludeFromBuild)'=='' OR 
    '$([System.Text.RegularExpressions.Regex]::IsMatch($(MSBuildProjectFullPath), 
    $(ExcludeFromBuild),  
    System.Text.RegularExpressions.RegexOptions.IgnoreCase))'=='False')" /> 
</Target>

You could always pass the particular projects you want to build as parameters to the MSBuild.

The MSBuild command line would look like this:

MSBuild /t:<Project Name>:Rebuild;<Another Project Name>:Rebuild

In TeamCity, you would put <Project Name>:<Target Action> in the target field in the MSBuild runner.

I add a system parameter under Parameters

• Name: system.ExcludeFromBuild
• Kind: System property (system.)
• Value: path to your csproj
