> I'm unfamiliar with the POM version coordinate system - any hints? My comment was in support of Laurent's proposal. I'm a relative maven newb, but this is my take: POMs use the concept of a coordinate, which is <groupId>:<artifactId>:<packaging>:<version> to identify a particular artifact e.g. library. GroupId + Artifact Id is a qualified name - think java package name. Packaging specifies how the artifact is packaged e.g. jar or war, but it doesn't contribute the id of the project. Version numbers are as you expect, but can be suffixed with '- SNAPSHOT', which effectively creates a distinct subspace of versions ordered by creation date. By depending on a 'a.b.c-SNAPSHOT' version, you get the latest (by date) artifact marked with 'a.b.c-SNAPSHOT'. When you release the artifact you remove the '-SNAPSHOT'. In effect the suffix creates two different versioning spaces, one of which is strictly determined by the hierarchic numeric ordering, and another that allows duplicates ordered by date within a specific hierarchically ordered version. AFAIK, an 'a.b.c-SNAPSHOT' version will not satisfy a request for 'a.b.c' e.g. -SNAPSHOT is not a further qualifier.
