ES6 + jQuery + Bootstrap - Uncaught ReferenceError: jQuery is not defined?

Question

How can I import jQuery as the dependency for bootstrap in ES6?

I tried with:

import {$,jQuery}  from 'jquery';
import bootstrap from 'bootstrap';

But I always get this error:

transition.js:59 Uncaught ReferenceError: jQuery is not defined

Which points to this file:

/* ========================================================================
 * Bootstrap: transition.js v3.3.7
 * http://getbootstrap.com/javascript/#transitions

 * ======================================================================== */


+function ($) {
  'use strict';

  // CSS TRANSITION SUPPORT (Shoutout: http://www.modernizr.com/)
  // ============================================================

  function transitionEnd() {
    var el = document.createElement('bootstrap')

    var transEndEventNames = {
      WebkitTransition : 'webkitTransitionEnd',
      MozTransition    : 'transitionend',
      OTransition      : 'oTransitionEnd otransitionend',
      transition       : 'transitionend'
    }

    for (var name in transEndEventNames) {
      if (el.style[name] !== undefined) {
        return { end: transEndEventNames[name] }
      }
    }

    return false // explicit for ie8 (  ._.)
  }

  // http://blog.alexmaccaw.com/css-transitions
  $.fn.emulateTransitionEnd = function (duration) {
    var called = false
    var $el = this
    $(this).one('bsTransitionEnd', function () { called = true })
    var callback = function () { if (!called) $($el).trigger($.support.transition.end) }
    setTimeout(callback, duration)
    return this
  }

  $(function () {
    $.support.transition = transitionEnd()

    if (!$.support.transition) return

    $.event.special.bsTransitionEnd = {
      bindType: $.support.transition.end,
      delegateType: $.support.transition.end,
      handle: function (e) {
        if ($(e.target).is(this)) return e.handleObj.handler.apply(this, arguments)
      }
    }
  })

}(jQuery);

Any ideas?

EDIT:

my gulp file:

var gulp = require('gulp');
var browserify = require('browserify');
var babelify = require('babelify');
var source = require('vinyl-source-stream');
var gutil = require('gulp-util');

gulp.task('es6', function() {
    browserify({
        entries: 'js/app.js',
        debug: true
    })
    .transform(babelify, { presets: ['es2015'] })
    .on('error',gutil.log)
    .bundle()
    .on('error',gutil.log)
    .pipe(source('compile.js'))
    .pipe(gulp.dest('js'));
});

gulp.task('default', ['es6']);

I've tried this answer and it worked.

// webpack.config.js
module.exports = {
    ...
    plugins: [
        new webpack.ProvidePlugin({
           $: "jquery",
           jQuery: "jquery"
       })
    ]
};
