My $.02

There are different audiences for different target distributions
  - binary distribution : end user (developer) or sysadmin
  - source distribution : a developer

Therefore a binary distribution must include the dependent libraries
to make it run out of the box.

That doesn't include tests because the audience for a binary
distribution doesn't run tests.

If someone wants to run tests they are a developer and should get a
source distribution.

The source distribution should NOT contain binary dependencies. In
this case Maven or another suitable build tool should resolve any
dependencies during the build stage.
