 *
 * If the build is being executed from the MASTER or SUPPORT branch, the artifacts from the stage repository
 * are downloaded and attached to the current build as if they were generated by the 'package' phase and checked by the
 * 'verify' phase (which should have happened as part of the build deploying to 'stage')
