"define" is not defined error. Broken build

[corbacho]

When building a custom jQuery (master branch) with this command:

grunt build:*:+core/ready

It will output about the line 47:

define("jquery", function(){});

This produces the error

ReferenceError: define is not defined

Why I'm using grunt build? I know that "grunt custom" is the recommended alias, but I'm trying to build a minimum possible jQuery that contains the necessary code for a reliable $(document).ready() . I want to propose this solution to be part of the upcoming Drupal 8 core, as an alternative to domready solution ​https://github.com/ded/domready that we are using now

The whole command is :

grunt build:*:+core/ready:+exports/global:-exports/amd:-ajax:-ajax/xhr:-ajax/script:-ajax/jsonp:-css:-deprecated:-dimensions:-effects:-event:-event/alias:-offset:-wrap:-sizzle:-queue:-data:-css:-selector:-traversing:-serialize

This builds a 11Kb size domready solution. 5Kb gzipped

Removing the buggy line mentioned before, it works: ​http://jsfiddle.net/WnhWc/2/

Ignore the jsfiddle link. These are correct:
The bug ​http://jsfiddle.net/WnhWc/4/
The fixed one (removing line 47) ​http://jsfiddle.net/WnhWc/3/

I reduced the bug to this command (building an empty jQuery)

grunt build:*

it contains these 2 lines:

define([]);
define("jquery", function(){});

Thanks for reducing it more. I'll mark this open, patches or further testing welcome.

Pull request that fix one of the issues:

define([]);

​https://github.com/jquery/jquery/pull/1569 Working now on fixing the other "define" that shouldn't be there (They are not related)
