How to mark an issue as Dupplicate of other in JIRA using JAVA code

[Shal]

Hi All,

I am new to this

I am tring to mark an issue as duplicate on another in JIRA.

String jsonRequest = "{\"update\":{ \"issuelinks\":[{\"add\":{\"type\":{\"name\":\"Duplicate\"},\"inwardIssue\":{\"key\":\"XTABC-123\"},\"outwardIssue\":{\"key\":\"XTDEF-456\"},\"comment\":{\"body\":\"Duplicate of XTDEF-456\"}}}]}}";

many people have suggested to use JSON object instead of String

converted it to Json object

final Gson gson = new GsonBuilder().setPrettyPrinting().create();
Object jsonObject = gson.fromJson(jsonRequest, Object.class);

but got this error

{"errorMessages":["Unexpected character ('u' (code 117)): was expecting double-quote to start field name\n at [Source: org.apache.catalina.connector.CoyoteInputStream@12cc67c1; line: 1, column: 3]"]}

Please suggest where i am getting wrong.

Hi @Shal , 

Did you check the string jsonRequest is json convertible ? 

Because as I see you can generate in other way

Thanks for reply  @Gonchik Tsymzhitov 

Is the added fields inside update in jsonRequest enough to mark one issue as duplicate of other?
