Based on discussion with @elukey and feedback on this commit, we think it would be a good idea to use Archiva to host the Java dependencies for datahub.
Referring to the instructions here: https://wikitech.wikimedia.org/wiki/Archiva#Uploading_dependency_artifacts
We should make available the following:
- jetty-runner-9.4.20.v20190813.jar
- jetty-jmx-9.4.20.v20190813.jar
- jetty-util-9.4.20.v20190813.jar
- jmx_prometheus_javaagent-0.16.1.jar
Other (e.g. more recent) versions might also work, but these are the versions of the files currently specified in the official datahub Dockerfiles.
