Question

looking to implement google closure with msbuild.
i found a few solutions but struggling to get it working.
any suggestions on how i can read multiple js files in and create .min versions during build?

thanks

EDIT: with the answer from below i was able to make some alterations with a view to fully implement what was recommended but in a simple form here is what i’ve wrote:

  <ItemGroup>
    <JSMin Include="$(OutputPath)Scripts\*.js"/>
  </ItemGroup>
  <Target Name="AfterBuild" Inputs="@(JSMin)" Outputs="@(JSMin ->'%(Directory)%(Filename).min%(Extension)')">
    <Exec Command="java -jar C:\temp\compiler.jar --js %(JSMin.Identity) --js_output_file C:\temp\%(JSMin.Filename).min.js"/>
  </Target>

the output path will be changed to a dynamic path later on.

many thanks

I haven’t looked at Google Closure, but you can run any command through the <Exec> task:

<Project DefaultTargets="build" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
    <Target Name="build">
        <Exec Command="echo Hello world"/>
    </Target>
</Project>

Edit: To run a command over a set of files:

<Project DefaultTargets="build" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <ItemGroup>
    <JSMin Include="jquery.js"/>
    <JSMin Include="somethingelse.js"/>
  </ItemGroup>

  <Target Name="build" Inputs="@(JSMin)" Outputs="@(JSMin->'%(Directory)%(Filename).min%(Extension)')">
    <Exec Command="java -jar C:\temp\compiler.jar --js %(JSMin.Identity) --js_output_file %(JSMin.Directory)%(JSMin.Filename).min%(JSMin.Extension)"/>
  </Target>
</Project>
