Practice As Follows
Try webjars. http://www.webjars.org/
It has all the major libraries, plus it’s in github, so you can fork your own versions if you really need to.
It should work well with a servlet 3 spec container with meta data scanning. But I use https://github.com/bazaarvoice/dropwizard-webjars-resource/ to serve it explicitly, since I’m using JAX-RS (using Jersey).
