+1.  Just ran into this myself.

There's a lot of dragons lurking in this area.  One of the ones that I
have had a lot of problems with are projects that include the -SNAPSHOT
suffix in the <version/>.  I would advocate that this is the wrong way
to do it because it breaks all the snapshot and release tools that are
built into maven itself.

Dentaku, XDoclet2, Mule, and all my internal projects use the
jar:install-snapshot goal as the default goal, which automatically adds
the suffix.  What's nice is that 'jar:snapshot-deploy' (for those with
correct privs) will push the jar from your repo to the correct staging
area for pushing to Ibiblio, without per-user files that need to be
modified in the RCS areas.  There are similar goals for released version

When used like this, there is no version number in the SNAPSHOT name,
i.e. 'jdo2-api-SNAPSHOT.jar'.  I agree that this is the correct
behavior, since developers who want to be on the bleeding edge and
always get the latest should not have to change the name of their
dependencies if there are releases on projects (thus changing the
version numbers).

Might want to look through the jars on Ibiblio for this one, most people
just use (for instance) jdo2-api-2.0a1.

Is there a definitive release nomenclature on this project yet?  Any
links if so?
