Exception while trying to read an issue using jira-rest-java-client

Alex Paransky

Dear Community,

I am using jira-rest-java-client to read an issue from JIRA Cloud

   <dependency>
      <groupId>com.atlassian.jira</groupId>
      <artifactId>jira-rest-java-client</artifactId>
      <version>2.0.0-m2</version>
   </dependency>

My code is fairly straight forward:

 

public static void main(String[] args) throws Exception
{
final JiraRestClientFactory 
        factory = 
new AsynchronousJiraRestClientFactory();

    final JiraRestClient 
        jiraRestClient =
            factory
                .createWithBasicHttpAuthentication(
new URI(Constants.JIRA_URL),
                    Constants.USERNAME,
                    Constants.TOKEN
                );

    final IssueRestClient
        issueClient =
            jiraRestClient.getIssueClient();

    final Promise<com.atlassian.jira.rest.client.domain.Issue>
        promiseIssue =
            issueClient.getIssue("OTPL-5018");

    final com.atlassian.jira.rest.client.domain.Issue
        issue =
            promiseIssue.claim();

    System.out.println(issue);
}

The issue is retrieved, but during the parsing of the author, the code is trying to retrieve attribute "name" which does not appear to exist in the JSON object.  

 

@Nullable
public static BasicUser parseBasicUser(@Nullable JSONObject json) throws JSONException {
if (json == null) {
return null;
   }
final String username = json.getString("name");
   if (!json.has(JsonParseUtil.SELF_ATTR) && "Anonymous".equals(username)) {
return null; // insane representation for unassigned user - JRADEV-4262
   }

// deleted user? BUG in REST API: JRA-30263
   final URI selfUri = optSelfUri(json, BasicUser.INCOMPLETE_URI);
   return new BasicUser(selfUri, username, json.optString("displayName", null));
}

Instead, my object contains a field called "displayName".

As a result, the code in the  jira-rest-java-client library fails with the following exception:

Caused by: org.codehaus.jettison.json.JSONException: JSONObject["name"] not found.
at org.codehaus.jettison.json.JSONObject.get(JSONObject.java:360)
at org.codehaus.jettison.json.JSONObject.getString(JSONObject.java:487)
at com.atlassian.jira.rest.client.internal.json.JsonParseUtil.parseBasicUser(JsonParseUtil.java:167)

Is there something that I am not doing correctly?  

Why does the object returned from JIRA Cloud does not include "name", but rather has "displayName" instead?  

More importantly, how do I fix this?

There are a plethora of different JIRA clients hosted at Atlassian Artifactory and one of the issues was to figure out which one to use.  From other googling around I found out that version 

 

<dependency>
    <groupId>com.atlassian.jira</groupId>
    <artifactId>jira-rest-java-client-core</artifactId>
    <version>5.2.1</version>
<dependency>

Corrects the issue that I was having.  In addition to this dependency, the following dependencies are also required:

<dependency>
    <groupId>io.atlassian.util.concurrent</groupId>
    <artifactId>atlassian-util-concurrent</artifactId>
    <version>4.0.1</version>
</dependency>

<dependency>
    <groupId>com.atlassian.jira</groupId>
    <artifactId>jira-rest-java-client-api</artifactId>
    <version>5.2.1</version>
<dependency>

<dependency>
    <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpclient</artifactId>
    <scope>runtime</scope>
</dependency>

<dependency>
    <groupId>com.atlassian.jira</groupId>
    <artifactId>jira-rest-java-client-app</artifactId>
    <version>5.2.1</version>
    <scope>runtime</scope>
</dependency>

After adding these dependencies, the error is gone and I am able to access JIRA Cloud REST API to complete the work I am doing.
