rollup js configuration - globals? - reactjs

Question

I got a project that is compiled with webpack and everything works well, but we are moving to rollupJS and i'm stuked with a file that is imported.
utils/init-jquery.jsx:
global.$ = global.jQuery = require('jquery');
require('jquery-mask-plugin');
require('fancybox')(global.$);
require('libraries/jquery.unserialize');
This file is imported for example in this file app.jsx:
import React from 'react';
import { render } from 'react-dom';
import InitJquery from 'common/utils/init-jquery';
import Init from 'common/utils/init';
...
I got stuked with this error in the console chrome:
Uncaught ReferenceError: global is not defined(…)
my rollup config:
var multiEntry = require('rollup-plugin-multi-entry');
var babel = require('rollup-plugin-babel');
var uglify = require('rollup-plugin-uglify');
var rollupIncludePaths = require('rollup-plugin-includepaths');
var nodeResolve = require( 'rollup-plugin-node-resolve');
var commonjs = require( 'rollup-plugin-commonjs');
var replace = require( 'rollup-plugin-replace');
const includePathOptions = {
paths: ['target/scripts'],
extensions: ['.jsx','.js']
};
var cache;
module.exports = function(grunt) {
return {
options: {
plugins: function () {
return [
rollupIncludePaths(includePathOptions),
replace({
'process.env.NODE_ENV': JSON.stringify( 'production' )

nodeResolve({ jsnext: true, main: true }),
