Resolving: MNG-885 o Extracting basedir from the project instance when PluginParameterExpressionEvaluator is init'ed if project != null...otherwise, using ${user.dir} from sysprops. o Extracting values for resolution from POM properties before POM instance during POM interpolation, and adding checks to guard against self-reference of POM elements. o Added three ITs (one contra) to test these resolutions.
