The error gives me the idea that somewhere it is also added as a lib in one of the components.
When you have added all the libs to manifest file it is not needed to also import them in the component.
is your jszip.min.js in globtecdevexcomponents/lib/js/jszip.min.js ? I can’t see it in Test/lib/js
Also i see a typo, you use a comma ‘,’ instead of semicolumn ‘;’ to separate jszip.min.js location from it’s name: should be globtecdevexcomponents/lib/js/jszip.min.js;name=jszip.min.js and not globtecdevexcomponents/lib/js/jszip.min.js,name=jszip.min.js
