[jocrau]

This causes automatic build pipelines to stop with the warning "Tried to use insecure HTTP repository without TLS.".

http:// should be https:// on lines

packages/jquery_2/build.boot

Line 20 in e0e943e

(download :url (format "http://code.jquery.com/jquery-%s.js" +lib-version+)

and

packages/jquery_2/build.boot

Line 22 in e0e943e

(download :url (format "http://code.jquery.com/jquery-%s.min.js" +lib-version+)

This might also apply to other packages.
