FR: help people spot *almost* unused dependencies

[iamdanfox]

What happened?

We recently found someone importing all of hadoop just for the Time class.

What did you want to happen?

It would great if we could somehow warn people that they're taking a huge dependency just for one class.

This can be done if switch to using the jdeps dependency analyzer (https://docs.oracle.com/javase/9/tools/jdeps.htm#JSWOR690). Can also use the --apionly option with that analyzer to be able to report what dependencies should be api vs implementation.
