Development work flows

[gkwan-ibm]

Make sure the Liberty Maven Plugin (LMP) can achieve the following development work flows:

• Develop a microservice
  • create a new maven project (min set of files and idea pom, etc)
  • start and develop the microservice (mvn liberty:dev)
    • change code - with compilation error
    • change configuration
    • remote debug
    • run unit and integration tests
    • stop the development with error and resume on next day 
  • add 3rd party library
• Develop 2+ microservices simultaneously
  • remote debug
  • run integration tests across microservices
• Build microservice by automation (Travis and/or Jenkin)
• Repackage microservice (e.g. update for new OL release, new dependencies, etc)

Including:

• open issues to enhance the LMP if necessary
• give suggestions to the guides
• document the detail of the above findings

This maps to OpenLiberty/open-liberty#9890.

Based on the research:

• Create a simple RESTful microservice
  • Cover HTTP methods: GET, PUT, POST & DELETE.
  • Add regular tests with plain java.
    • @DisplayName.
    • @order.
    • Test all 4 HTTP methods.
  • Add MST using @restclient annotation
    • @DisplayName.
    • @order.
    • Test all 4 HTTP methods.
  • Add liveness & readiness checks.
  • Use a microprofile configuration file to set maintenance to true or false.
  • Also defined in server.xml for dynamic changes.
  • Use Open API
    • Add Annotations

RH folks are looking into the issue that prevents the OL samples from Purple Liberty to be deployed on OS v4. (Currently broken in production)

Issue: https://groups.google.com/u/3/g/fabric8-launcher/c/w5A7tewzFCE

Once it is fixed, we can test our changes.

The templates have been fixed and the updates merged for Purple Liberty.
