From 2e005b107e6abda5bf09a963a54833cedabfba99 Mon Sep 17 00:00:00 2001

From: Roland Grunberg <rgrunber@redhat.com>

Date: Wed, 18 Jun 2014 13:01:31 -0400

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.
