I am responding on the dev list too :-) There's two things going on:

1) An automated build numbering -- and any build numbering for that 
matter -- isn't needed for official distributions. All you need is the 
X.Y.Z scheme where X=major,Y=minor,Z=revision versions.

2) You are actually using the build numbering to track your snapshots. 
That's what the build number is really for. When you use maven and 
attach -SNAPSHOT suffix to the version number, the libraries get 
deployed to the snapshot repository with an automated build number.

So two things to remember: build numbers are for development 
distributions only. The build number will be updated for every snapshot 
distribution. Once you're ready to attempt an official release, remove 
-SNAPSHOT and then you have the next X.Y.Z version.
