In the current release, the process to generate the swager-ui has changed and we generate it from openapi.yaml instead of code. It gives flexibility and code and documentation are decoupled. 

There are still some open issues with it.

1. Missing ncmp endpoints from swagger-ui
2. To keep the openapi yamls in the docs folder and add steps in the maven build to copy it from docs to resources/static. cps-temporal can be used as a reference.
