/**
 * Setup a temporary project on the fly, uses Spock.
 *
 * Caveat, this is ONLY setting up the Project data structure, and not running through the completely lifecycle, Like to
 * see http://issues.gradle.org/browse/GRADLE-1619
 *
 * Its value lays in being able to execute method with a proper Project object, which can flush out most groovy functions,
 * finding basic compiler like issues.
