Trouble using browserify-shim with grunt-browserify

[lelea2]

I have trouble with using grunt-shim with grunt-browserify.
So basically, i have shim configured in package.json

 "browser": {
    "jquery": "./node_modules/couponscom-js-lib/lib/jquery.js",
    "underscore": "./node_modules/couponscom-js-lib/lib/underscore.js",
    "backbone": "./node_modules/couponscom-js-lib/lib/backbone.js",
    "pubsub": "./node_modules/couponscom-js-lib/lib/PubSub.js",
    "dust": "./node_modules/dustjs-linkedin/lib/dust.js",
    "dust-compiler": "./node_modules/dustjs-linkedin/lib/compiler.js",
    "dust-helpers": "./node_modules/dustjs-helpers/lib/dust-helpers.js",
  },
  "browserify-shim": "./tasks/shim/shim.js",
  "browserify": {
    "global-transform": [
      "browserify-shim"
    ]
  }

under tasks/shim/shim.js

module.exports = {
    'jquery': {
        'exports': 'jQuery'
    },
    'underscore': {
        'exports': '_'
    },
    'backbone': {
        'exports': 'Backbone',
        'depends': {
            'jquery': '$',
            'underscore': '_'
        }
    },
    'pubsub': {
        'exports': 'PubSub',
        'depends': {
            'backbone': 'Backbone'
        }
    },
    'dust': {
        'exports': 'dust'
    },
    'dust-compiler': {
        'depends': {
            'dust': 'dust'
        }
    },
    'dust-helpers': {
        'depends': {
            'dust': 'dust'
        }
    }
}

Doing some googling and realize i have to duplicate shim on grunt file

var fs = require('fs'),
    shims = require('../shim/shim.js'),
    alias = require('../shim/browser.js'),
    sharedModules = Object.keys(shims).concat([
      // place all modules you want in the lib build here
    ]);

module.exports = function browserify(grunt) {

    // Load task
    grunt.loadNpmTasks('grunt-browserify');
    var browserifyProduction = {
            options: {
                browserifyOptions: {
                    debug: false
                },
                require: sharedModules,
                preBundleCB: function (b) {
                    b.transform({global: true}, 'browserify-shim')
                }
            },
            files: [{
                expand: true,
                cwd: 'public/js/',
                src: '*.js',
                dest: 'build/js'
            }]
        }

All shimmed files are pulled in, however i have trouble with the "require" part. jQuery is pulled in for example, but it's said jQuery not defined when run in browser, realize that the hash is not maintained as the old grunt

Anyone has the same issue and know how to fix it?

Thank you
