The problem is what the error tells. You should load the jquery before
CKEditor jQuery adapter. However, you may not load the jquery library in your code.
Note that adapters/jquery.js is not Jquery library but a jquery adapter as it contains below description:
jQuery adapter provides easy use of basic CKEditor functions and access to internal API. It also integrates some aspects of CKEditor with jQuery framework
Again, please add jquery library in your code and put it before the ckeditor and jquery adapters as below exmple (you could choose whatever version of jquery to fit your project):
Hope this can help you.
