Minor Description
We can, and should, remove the buildnumber-maven-plugin. It was originally added to track different SNAPSHOT versions between releases, to ease debugging. However, I don't believe that is a situation that is likely to happen, or should be supported if it does. Using SNAPSHOT builds should be "at your own risk" and unsupported.
Further, it is complicated by the fact that we share SVN repo revision numbers with the other ASF projects and so a wide range of build numbers may represent the same Accumulo revision.
Removing this should simplify the POM a little bit (especially the maven-jar-plugin configuration), speed up the build slightly, and make the project more portable between SCM systems.
