Description

Is your feature request related to a problem? Please describe.
JVM packages are not supported at all.

Describe the solution you'd like
Support JVM packages (i.e. jars) on Maven Central.

Describe alternatives you've considered
N/A

Additional context
Domain ownership of the group ID is already validated by maven central, So ownership can either be done via that (i.e. requiring the MCP name match the group/artifact), or an attribute in the published POM.

Start by tracing how the registry currently identifies and validates packages, then compare the Maven Central group/artifact and published POM ownership options described here. Done means JVM JAR packages from Maven Central can be registered with an agreed ownership check.
