This is not our version, its the version of the spec.
Its still a version number in an artifactId... regardless of who's
version it is.
The problem with this is that when you go to change versions you have
to go update a bunch of poms to fix their artifactId instead of
simply updating one dependency in a dependencyManagement section.
Because we put version numbers in artifactIds we've given ourselves a
lot more maintenance work when it comes time to rev specs and because
of this we have made it far to easy to missing them and get modules
out of sync.
IIRC we had a big discussion about the best spec naming convention
and decided this was it.
So because of that its not something that can be changed? I really
disagree with this practice. It really only make *more* maintenance
work and increases the chances of something getting out of sync. Its
far to easy to end up with several different versions of the same
spec in a project because the normal maven version resolution can't
figure out which one to use because of the version information
encoded in artifact ids.
Despite our best intentions, we often end up releasing corrections
to spec jars we've published. Can you suggest a different naming
convention that will clearly and unambiguously show both the spec
version and the geronimo version of a spec jar? Or do you think
one of these is unnecessary?
I think that all relevant information can be encoded in the artifacts
version. And I think that the geronimo version is mostly irrelevant,
its basically a revision of the sun version, so I would just put a
counter on the end of the sun version:
<specVersion>-<geroniomRev>
1.0-1
This helps do away with inconsistencies which we have now, with
picking 1.1 or 2.0 or 1.0m2 or whatever... just keep incrementing the
revision when there are changes.
Some real examples:
<current> ---> <suggest> (w/o version in artifactId):
geronimo-j2ee-management_1.1_spec-1.0-M1.jar -> geronimo-j2ee-
management-spec-1.1-1.jar
geronimo-j2ee-management_1.0_spec-1.0.jar -> geronimo-j2ee-management-
spec-1.0-1.jar
geronimo-j2ee-management_1.0_spec-1.0.1.jar -> geronimo-j2ee-
management-spec-1.0-2.jar
geronimo-j2ee-management_1.0_spec-1.1.jar -> geronimo-j2ee-management-
spec-1.0-3.jar
As you can probably tell, I think this is a very good practice. I
hate it when someone says they depend on "servlet.jar" and I have
to open the spec jar up and try to figure out if whoever generated
it bothered to include any information at all about which spec
version they implemented.
Well, lucky for you w/maven the version information is encoded in the
jar file names by default. So its quite easy to just use the
"version" of an artifact to contain all of the versioning details and
you will end up with an artifact with that information in the filename.
