Description

There is couple of dependency issues in the current maven config. This is then leaking into the integrating project which then needs to specify foreign dependencies just because arrow doesn't list them properly or is pulling unnecessary dependencies just because arrow lists them improperly.

Here is the current report for each of the arrow's modules:

I am proposing to add the maven-dependency-plugin to guard the dependency configuration always stays consistent.
