Uncaught ReferenceError: $ is not defined when debugging jQuery

I created a web module app in Intelli J 12 (pure html, css3 and Javascript) and downloaded jQuery and jQuery UI.

jQuery is not working and when I debug I get :Uncaught ReferenceError: $ is not defined <- which says that jQuery is not loaded.

So what am I missing? why is jQuery not loading?

Both jQuery libraries are in the global libraries configuration for the project.

After linking the script to the html my first line in the script is:

$(document.ready(function(){"code here"});

Regards,
