VOLTHA/ONOS job failed when maven central packages are MIA.

A cryptic job failure can occur when dependent packages are missing from maven central.
{{}}
Underlying problem seems due to version strings not being updated or are wonky: * between VOLTHA and ONOS.

• ONOS packages published to maven central.{{}}

{{}}
Could not find artifact org.opencord:olt-app:oar:5.2.1 in central (https://repo.maven.apache.org/maven2{{) }}
 
Research what can be done to make this condition more visible: # Document development flow.

1. Automation - commits/job should be able to detect some version problems based on string compare (v5.1.2 != v5.2.1).
2. Jenkins can perform an artifact validation stage – verify all dependent artifacts and version strings exist and are reasonable VS failing due to something missing.

Hi @channel after merging Patch 33257 I thought Gustavo's improvements regarding pending flows in ONOS will be released, but I see the same issue in pipeline Unitag Subscriber TT. With Gustavo's image silvagu/voltha-onos:4765 the issues were disappeared. Four days ago Gustavo release olt-app version 5.2.1, right? But in Logs I found: olt-app/[5.1.2,5.1.2]. I'm not sure what is really running. Could you please check if the current ONOS version includes latest olt-app? Thanks

I retested Gustavo's Image with https://jenkins.opencord.org/view/VOLTHA-2.X-Tests/job/periodic-voltha-unitag-subscriber-tt-test-bbsim/375/ successfully, as expected. So there is something missing in the current ONOS Version of master used in pipelines. Please check, thanks a lot. Torsten

I guess we also have to integrate this one:

Thanks @Gustavo Silva for the patch.
For some reason the sanity test seems to fail. Do you mind checking this when you can.
Below is the error I could find from the logs
[2022-09-19T16:41:37.294Z] [ERROR] Failed to execute goal org.apache.maven.plugins:maven-dependency-plugin:3.0.1:copy (default-cli) on project fake: Unable to find/resolve artifact.: Could not find artifact org.opencord:olt-app:oar:5.2.1 in central (https://repo.maven.apache.org/maven2) -> [Help 1]
 
 Well, it seems there's still something missing in this process.Voltha-onos uses the apps available on maven's central repository, if you take a look here: https://repo.maven.apache.org/maven2/org/opencord/olt/, you'll see there's really no 5.2.1 version. (edited)

I am unsure how how apps are loaded to maven central repository. I assumed it be would be done automatically on olt app merge - i guess that did not happen.
 
 [....]what is the process for onos apps to be loaded to maven repo?

That would explain, why I see 5.1.2 instaed of 5.2.1.
