java - jsonschema2pojo generating enum without any key value pairs -

i using jsonschema2pojo generate pojo json schema.however, not seem working when using named enums.instead of key value pairs in pojo, adds __empty__. there problem way have specified enums or issue jsonschema2pojo?

json schema

{  	"type": "object",  	"$schema": "http://json-schema.org/draft-04/schema",  	"description": "status identifier",  	"properties": {  		"status": {  			"type": "string",  			"enum": [  				{"active" : 0},  				{"inactive" : 1}  			],    			"description": "defines whether  schedule active"  		}  	}  }

generated java pojo

note - works fine if remove enum names , specify values below

{  	"type": "object",  	"$schema": "http://json-schema.org/draft-04/schema",  	"description": "status identifier",  	"properties": {  		"status": {  			"type": "string",  			"enum": [  				"active" ,  				"inactive"   			],    			"description": "defines whether  schedule active"  		}  	}  }

[edit]

tl;dr: defining key-value pairs instead of json array, schema not in fitting json-schema.org's definition.

[/edit]

in java, an enum best used either creating singleton or enforcing value fixed number of constants. fixed set of constants value list.

that being said, since (first) json schema's definition of status property it's string , can value of set of objects, opposed value of set of values. in other words, according documentation jsonschema2pojo on defining enum, there no example of set of objects, set of values. it's expecting list of values , nothing more.

your example @ end of question, "it works fine if remove enum names , specify values below," successful result because defining property build out enum according jsonschema2pojo expecting.

my recommendation: use last example , either build separate map<string, integer> pair "active" , "inactive" values numeric representations (if expect have larger list), or set couple constants map numeric value (e.g.- private static int active = 1;), needs may be.
