Setup publishing to Maven Central

[steve-todorov]

Task Description

We used to publish our artifacts to JCenter. Unfortunately, as of May 2021 package publications to JCenter have been halted as part of the plan to sunset the JCenter service (more here).

As a result, we need to start publishing our artifacts to Maven Central instead of JCenter.
