MSBuild conditional Exec?

Question

I am building various projects using the

E.g

Answer 1

You should be able to use the TargetOutputs parameter:

<MSBuild Projects="" >
   <Output TaskParameter="TargetOutputs" ItemName="AssembliesBuiltByChildProjects" />
</MSBuild>
<Message Text="Assemblies built: @(AssembliesBuiltByChildProjects)" /> <!-- just for debug -->
<Exec Command="" Condition="'@(AssembliesBuiltByChildProjects)'!=''" />

Answer 2

If you can add the following to each of your projects:

<Target Name="DoStuffWithNewlyCompiledAssembly">
    <Exec Command="" />
</Target>

... then you only need to add a property:

<Target Name="Name">
  <MSBuild Projects="" Properties="TargetsTriggeredByCompilation=DoStuffWithNewlyCompiledAssembly" />
</Target>

This works because someone smart at Microsoft added the following line at the end of the CoreCompile target in Microsoft.[CSharp|VisualBasic][.Core].targets (the file name depends on the language and MSBuild/Visual Studio version).

<CallTarget Targets="$(TargetsTriggeredByCompilation)" Condition="'$(TargetsTriggeredByCompilation)' != ''"/>

So if you specify a target name in the TargetsTriggeredByCompilation property, your target will run if CoreCompile runs-- and your target will not run if CoreCompile is skipped (e.g. because the output assembly is already up-to-date with respect to the code).

Answer 3

I did manage to find a solution to fit my needs although it may not be the optimal solution.
