We publish our artifacts in Maven Central on release, and I understand all the dependencies should be resolvable on Maven central too. At least, this is the latest understanding I have.

IFF the initial statement is true, then xerces:xercesImpl:jar:2.12.0.SP02 is not available on Maven central,
yet kie-camel depends on it: https://github.com/kiegroup/droolsjbpm-integration/blob/800f3805ce55c1cf13d4f1b415d257698a4a1e7d/kie-camel/pom.xml#L153-L156
because the kie-parent defines to use the .SP02 version after migrating away from ip-bom: https://github.com/kiegroup/droolsjbpm-build-bootstrap/blame/master/pom.xml#L280 (permalink here)

This ticket will reconsider the modification to kie-camel due to this: RHDM-851 as after a throughout investigation it seems the xercesImpl might actually not be needed at all.
