Creating subtask using java rest api client

[samkit jain]

Hi All,

I am working on a requirement where I have to create an issue and multiple sub task for that issue using java rest client for jira.

when I am trying to create an issue using sub-task issue type id, it is giving me error that parent Id or key not mentioned.

I am using JIRA Rest API v5.1.0, but in the Inputbuilder class, there is no option to state the parent key or id.

Can anybody please help?

P.S : Due to confidentiality constraint, I cannot copy my code here. Any help would be highly appreciated.

Hello @samkit jain 

Please share your code sample and also the link to the Jira REST client docs

Hi @Tarun Sapra ,

I cannot share the code due to client confidentiality agreement. However I was able to resolve the error.

following thing worked for me:

While creating IssueInputBuilder Object for Subtask issue, I set a parameter name FieldInput.

FieldInput fi = new FieldInput("parent", Object)

This Object is a ComplexIssueInputFieldValue type.

Hi @samkit jain 

 I am meeting the same issue here, Could you please share a sample of data you put in this ComplexIssueInutFieldValue type? thx.

Here's a (non-performant) snippet showing how to create an epic and then make a subtask for it:

import java.io.IOException;
import java.net.URI;
import java.net.URISyntaxException;
import com.atlassian.jira.rest.client.api.JiraRestClient;
import com.atlassian.jira.rest.client.api.domain.BasicIssue;
import com.atlassian.jira.rest.client.api.domain.input.ComplexIssueInputFieldValue;
import com.atlassian.jira.rest.client.api.domain.input.IssueInput;
import com.atlassian.jira.rest.client.api.domain.input.IssueInputBuilder;
import com.atlassian.jira.rest.client.internal.async.AsynchronousJiraRestClientFactory;
public class Application {
  public static void main(String[] args) throws IOException, URISyntaxException {
    final AsynchronousJiraRestClientFactory factory = new AsynchronousJiraRestClientFactory();
    URI jiraServerUri = new URI("my jira base url");
    final JiraRestClient restClient = factory.createWithBasicHttpAuthentication(jiraServerUri, "username", "password");
    try {
      IssueInput epicInput = new IssueInputBuilder()//
          .setProjectKey("Project Key")//
          .setIssueTypeId(36L)//
          .setSummary("Epic W/Rest API")//
          .setDescription("my epic description")//
          .build();
      BasicIssue epicIssue = restClient.getIssueClient().createIssue(epicInput).claim();
      IssueInput subTaskInput = new IssueInputBuilder()//
          .setProjectKey("Project Key")//
          .setIssueTypeId(5L)//
          .setSummary("Subtask W/Rest API")//
          .setDescription("my subtask description")//
          .setFieldValue("parent", ComplexIssueInputFieldValue.with("key", epicIssue.getKey()))//
          .build();
      restClient.getIssueClient().createIssue(subTaskInput);
    } catch (Exception e) {
      e.printStackTrace();
    } finally {
      restClient.close();
    }
  }
}

 you can query things like id of subtask issue type etc by getting 

${base jira url}/rest/api/2/issue/createmeta

you'll need the following dependencies:

<dependency>
  <groupId>com.atlassian.jira</groupId>
  <artifactId>jira-rest-java-client-app</artifactId>
  <version>5.2.1</version>
</dependency>
<dependency>
  <groupId>io.atlassian.fugue</groupId>
  <artifactId>fugue</artifactId>
  <version>4.7.2</version>
  <scope>provided</scope>
</dependency>
