[JAVA] [Resttemplate Client] Empty authNames in generated API classes

Description

Hi everybody. I have an strange behaviour after generating code with resttemplate client library. Our swagger document has securityDefinitions

securityDefinitions:

  default:

    type: oauth2

    authorizationUrl: 'https://beholdertest.minessotta.es:443/authorize'

    flow: implicit

    scopes: {}

After running the generator, the api classes contains the authnames arrays empty.

 String[] authNames = new String[] {  };

I have modified the method

public CodegenOperation fromOperation(String path,String httpMethod,Operation operation,Map<String, Model> definitions,Swagger swagger)

from DefaultCodegen.java

in order to include the neccesary information (according to the mustache template)

List<CodegenSecurity> allMethods = new ArrayList<CodegenSecurity>();
        Map<String,SecuritySchemeDefinition> secDefinitions = swagger.getSecurityDefinitions();
        
        if (secDefinitions!=null && secDefinitions.size()>0){
        	for (Entry<String, SecuritySchemeDefinition>current:secDefinitions.entrySet()){
        		CodegenSecurity newSecurity=fromSecurityDefinition(current.getKey(),current.getValue());
        		allMethods.add(newSecurity);
        	}
        }
        op.authMethods=allMethods;

 private CodegenSecurity fromSecurityDefinition(String key, SecuritySchemeDefinition value) {
    	CodegenSecurity sec=new CodegenSecurity();
    	sec.name=key;
		return sec;
	}

I think the CodegenOperation object does not have the infor regarding security definitions. So, that might be the reason for generate and empty authNames array.

Thanks a lot in advance

Kind Regards

Begin with DefaultCodegen.java's fromOperation method and the RestTemplate mustache template that consumes authNames. Reproduce the issue with the supplied Swagger document and generation command, then verify that generated API classes populate authNames from the declared securityDefinitions.
