Custom Aggregation added: Invalid Aggregators name

[noureentaj]

What Happened:

I created an Aggregator plugin, and followed all instructions as provided on the documentation.
For annotations, I have used PluginName property on my Java Class for the name and description that I expect to see on UI. I couldn't find AggregatorName interface anywhere in the repository to import.

I then downloaded a build, and added the jar file to the lib folder, and also added relevant properties file on the conf directory. Made the necessary datastore changes in the kairosdb.conf file. I ran kairosdb.sh script right after. The logs are clean, and it seems that the custom aggregation is being detected properly without any failure logs (I used to get them before and now I dont!).

Issue

I can't see the custom aggregation on kairos UI. I cant even hit the query REST API with payload with my aggregation. This is the error I get on response:
query.metric[0].aggregators[0].myaggregation invalid aggregators name

Is there any additional validation or a script that has to be executed to detect or validate the plugin, other than the properties file?
Please help!
I also need explicit instructions on how I can deploy my plugin. The documentation seems to be outdated, there's no Makefile and the Dockerfile needs to be updated otherwise!

Thanks a ton in advance!
