Unified source directory

 Unified source directory structure that is analogous to the repository
 itself. This way locations of intermediary artifacts of a build would be
 in a known location. This would also help with developer setup i.e. getting
 new developers up and running. They could run a maven command and have all
 their source trees set up in the same way as their colleagues.

   | This is a list of profiles which can be activated in a variety of ways, and which can modify
   | the build process. Profiles provided in the settings.xml are intended to provide local machine-
   | specific paths and repository locations which allow the build to work in the local environment.
   |
   | For example, if you have an integration testing plugin - like cactus - that needs to know where

        <field xdoc.separator="blank">
          <name>parent</name>
          <version>4.0.0+</version>
          <description>The location of the parent project, if one exists. Values from the parent
            project will be the default for this project if they are left unspecified. The location
            is given as a group ID, artifact ID and version.</description>
