Clone Issue in java with rest api

Julien_u2jcnc

Hello,

I would like to clone an issue using rest api. I've already checked on Internet and for what I've found there is no easy way to do this. I'm getting JSONObject from a get request and I would like to create a clone of this issue using this json, Therefore I do it manually. However I'm facing 2 issues.

1) There is a lot of customfields with null value, I did a recursive loop to get rid of all of these. Is there a way to just ignore them when value is null, otherwise not ?

2) It's not simple tickets. I mean there is issuelinks, attachment ... I found that I have to use many rest apy to perform it, is that right ? It means for each jsonObject I have to manually detect these special fields and then use the correct api ? (https://docs.atlassian.com/software/jira/docs/api/REST/7.6.1/?_ga=2.6947120.32031392.1541399805-1750503480.1538466569#api/2/field-createCustomField)

I would like to precise that it's not an authentification problem. I can succesfully create a simple issue with only project, summary, description and issuetype.

Thank you.

Yes I simply delete all custom fields or null fields. Thank you

Have you found an answer to your issue? I am also looking for a script/API to clone an issue using REST APIs.

I do not understand.

I am trying to clone a JIRA ticket. How do accomplish this, And would you mind sharing code? Are you using JIRA module in your Python script?

Hi here is a part of my code. I'm not using any module. I'm using java. You just have to reach rest api with HTTP request.

URL jiraURL = new URL(this.hubModel.getUrl() + "/rest/api/2/issue/");
URLConnection urlConnection = jiraURL.openConnection();

String login = this.hubModel.getIdUser() + ":" + this.hubModel.getPwUser();
byte[] authEncBytes = Base64.encodeBase64(login.getBytes());
String encoded = new String(authEncBytes);

byte[] dataBytes = newJsonObjectIssue.toString().getBytes("UTF-8");

// establish connection and request properties
connection = (HttpURLConnection) jiraURL.openConnection();
connection.setRequestMethod("POST");
connection.setRequestProperty("Accept", "*/*");
connection.setRequestProperty("Content-Type", "application/json");
connection.setRequestProperty("Authorization", "Basic " + encoded);
connection.setUseCaches(false);
connection.setDoInput(true);
connection.setDoOutput(true);
DataOutputStream wr = new DataOutputStream(connection.getOutputStream());
wr.write(dataBytes);

System.out.println("Connection Response: " + connection.getResponseCode() + ": " + connection.getResponseMessage());

wr.flush();
wr.close();

Reader in = new BufferedReader(new InputStreamReader(connection.getInputStream(), "UTF-8"));
String responseMessage = "";
for (int c; (c = in.read()) >= 0; responseMessage += ((char) c))
;
System.out.println(responseMessage);
JSONObject responseMessageJson = new JSONObject(this.removeUTF8Mistakes(responseMessage));
this.newKey = responseMessageJson.getString("key");
this.fillIssue(this.newKey, responseMessageJson.getString("id"), responseMessageJson.getString("self"));

I Max,

There is no api to do so, you have to do it manualy, also create a new issue with extracted info from your old issue.

Yikes. I only know Python. I would have to read/learn your code and try to figure it out and how to use it. I will certainly try. In order to run this, did you need any libraries or modules from Jira when you compiled your code with jvm?

This is basically what I am about to do also. Seems like you need to read the original, copy all the custom field data, prepare a new issue, and then create it. Also, if you want to link it, use the return data from the Create Issue to do the link back.

Hi Cameron. I am still looking how to do this. I do need to read the original, copy some custom field data, and prepare a new issue. I am a Python dev, and not a Java developer. But at this point, this need is still quite important to our team, and we want to find a solution to it. Can we work together on this?
