Interfaces are not getting generated for the generated Model classes .
Is there any options to be enable the generation of the interface? ( something like <withInterfaces>true</withInterfaces>

Start with the Maven configuration shown for the jaxrs-cxf generator, especially generateModels, generateInterfaces, and the commented withInterfaces option. Trace how the generator handles the MAS_api.yaml input and determine the expected model-interface output; the work is done when interfaces are generated alongside the model classes.
