No, I am being unclear because I am not certain of the details. 

Maven has two types of repository, those where 'snapshot versions' 
are allowed and those where they are not. 

The difference is that in addition to the file's version the file also has a date 
incorporated into its name. 

If I deploy a.jar at version 1.3 the file name in a non-snapshot repository will be a-1.3.jar.

However if I deploy to a snapshot repository then the file name will be,  for example: 
http://paneris.net/maven2/de/fuberlin/wiwss/ng4j/ng4j/0.9-SNAPSHOT/ng4j-0.9-20090606.175554-1.jar
I think that this is artefact id + version + date + time + serial 

So when a dependency has the special tag SNAPSHOT then Maven goes and checks 
the remote repository for the most recent version, even if it has a locally cached copy 
which matches on version number alone.

Certainly in the POM and probably in build.xml we should use SNAPSHOT.
