Description

Right now we have ${project.*} which always interpolates values based on the final project: "classical" interpolation is "late" interpolation. So it is not possible that parent poms can lock values, ie avoid child poms override. By adding ${this} for "early" interpolation, it will be possible to have intermediate interpolation.

If a pomfile depends on a parent, that parent will first resolve all ${this.*} values for itself. Once the fully inherited pom is there, all ${project.*} will be resolved.
