Jira Cucumnber test automatization

In order to automate my browser frontend tests I plan the following:

Create a .feature file via XRAJ for JIRA, automatically export the file, and execute it on a virtual machine in connection with cucumber, selenium and java. Next step is to automatically import the generated JSON (including the test results) into XRAJ (where the results will be evaluated).

My problem now is, that I don’t really know how to start this project. First steps I already did are: I configured Cucumber and Selenium for JAVA, I can execute feature files as Junit tests and export them as JSON. Also I’ am able to create .feature files in XRAJ, export them manually, execute the tests, and import the results… but as I already said every step in the manual way.

Do you guys have any idea, how I can reach my goal of full automatic test execution ? I have read about the JAVA REST API, but I actually have no idea of how to successfully integrate the REST API into JAVA and XRAJ.

My dream is to create the .feature file in XRAJ, press the execute button in XRAJ, see the tests results in XRAJ, and everything else would happen in the background.

Thank you very much for your help. !
