I'm creating an automated web app build process with node.js on windows. I'm trying to run our code through Google closure java program. I read the documentation on child_process in the node documents. It mentions it doesnt work in windows yet. Is there a package or work around for this?

Heres the code im trying to run.

var _exec = require('child_process').exec;

_exec( 'java ' + '-jar '+ COMPILER_JAR +' --js '+ srcPath +' --js_output_file '+ distPath, 

    function(e){

        echo( google closure done....);

        echo( e );

    } );

I have a web server app for controlling a queue of builds on windows XP and I used it to run batch files or executables without any additional packages.

I would check the error parameter on the callback and stderr as this may help you find the reason it does not work.

My example solution out of my server which I hope helps:

var theJobType = 'FOO';

var exec = require('child_process').exec;

var child = exec('Test.exe ' + theJobType, function( error, stdout, stderr) 

   {

       if ( error != null ) {

            console.log(stderr);

            // error handling & exit

       }



       // normal 



   });
