Is there a way to set the classpath for all Junit tests runs at one
time?  Currently it seems I must define the classpath for each test
case, even though all the test cases require the same classpath.

Also, is there a way to conveniently store launch definitions and
project build paths in the source code control system?  It seems that
everytime we need a new library, all N developers have to go add that
library to the class path for their project.  I'm used to storing all
this stuff in a Makefile that is checked in to the source code control
system, so that when one developer adds something, everyone else can
see it.  But with Eclipse it seems that there are any number of actions
that must be repeated by every developer on the team.
