For versions I think it is a bit more complicated as Maven
differentiates snapshot and release artifacts.
For snapshot artifacts, I would use x.y.z-SNAPSHOT in Maven and
x.y.z.qualifier in OSGi. This results in discrepancy between expanded
-SNAPSHOT and .qualifier for deployed artifacts but I do not think there
is a way around it.
For release artifacts, I think Maven and OSGi versions should be the
same and the best I can suggest is to use x.y.z.<EXAPNDED-QUALIFIER>.
This breaks normal Maven version progression (i.e. x-SNAPSHOT => x),
however.

I originally hoped that some clever naming scheme would allow resolution of

not come up with such a scheme and eventually convinced myself it was not
possible (but I'd be happy to be proved wrong here).
I still believe artifactId == bundleId convention makes sense, but it is not
enforced in Tycho.
I would also use OSGi versions (i.e., major.minor.micro) and use -SNAPSHOT
in manen and .qualifier in OSGi. Again, this is not enforced in Tycho.
Apart from than, I would just follow Maven best practices.
Please let me know if my understanding is correct. All else being
equal, it seems like new Maven bundle projects would use the following
patterns:
Names:
${project.artifactId} = Bundle-SymbolicName = root package. No dashes
used, only dots.
e.g.
<groupId>org.group</groupId>
<artifactId>${project.groupId}.some.artifact</artifactId>
with the Bundle-SymbolicName: org.group.some.artifact
and the project root package: org.group.some.artifact
Versions:
Maven version = Bundle-Version except for '-' vs '.' before qualifier.
majorVersion, minorVersion, and incrementalVersion are numeric and
required. incrementalVersion is alphanumeric and optional.
i.e.
majorVersion.minorVersion.incrementalVersion(-qualifier)? in Maven and
majorVersion.minorVersion.incrementalVersion(.qualifier)? in OSGi's
Bundle-Version
Thoughts?
