How are you ending up with anything other than the version you specify? Dependency mismatches on versions?

More info, including an example of Maven itself shipping with mismatched versions: http://jira.codehaus.org/browse/MDEP-273

Depending on how bad the mismatch is and how carefully people maintain or break APIs between versions, it can introduce problems.

I've not been into Java enough recently to know if this is fixed or is still affecting Maven3.
