From: Roland Grunberg <rgrunber@redhat.com>

Subject: [PATCH 3/6] Tycho should always delegate artifact resolution to
 Maven.

Maven resolves dependencies from the following locations in the
following order:
    * reactor,
    * workspace (eg. XMvn),
    * local repository,
    * remote repositories.

Tycho assumes that all resolved artifacts are present within the reactor
cache but this is not true for artifacts resolved from workspace
locations.
