Unlike JCenter, Maven Central requires a <name> tag in the POM. The Sonatype upload tool gets confused by artifacts called *-release.jar, but the versioning rules should treat 0.0.12 as higher than 0.0.12-dev-40245c4a:
All versions with a qualifier are older than the same version without a qualifier (release version).
For example:
1.2-beta-2 is older than 1.2.
