Yes, it means the version is missing.

I'm not a maven expert, but I think there are several possible reasons
why this happens only to some artifacts:
- a parent pom defines a version
- a referenced pom defines a version
- you already have downloaded that artifact and maven has noted (don't
know how) that a specific version is the latest.

To keep it short :) - we should always specify a version for a
dependency - either directly in the pom or in a dependency managemenet
section of a parent pom.
