I’m trying to use jsonschema2pojo to convert the FHIR schema to a java object. If I use this example schema then the generated java classes are create just fine, but when I use this Json Schema then nothing is created and I don’t see any errors to understand why its not created. Can anybody help me understand where the failure is?

My pom file
