Task Connector Plugin Persistance Not working Even with Tag

Hello,

I have built a new task connector and it works fine, but the server configuration is not persisted across restarts of the IDE. I have also added a tag annotation as recommended by this post. However, my configuration is still not persisted across restarts. Is there anything else I am missing? an API key, or tag naming convention in relation to my classes?

I am on 15.0.4 of Ultimate.

Thanks,

Wes
