JIRA - Java Rest Client Get Issues Error

[ragipally alekya]

Hi everyone,

I am a newbie who started to integrate JIRA using Java, following the issues & document, I am trying to get issues using Java.

Everything's fine, but I am getting the following error.

Exception in thread "main" java.lang.IncompatibleClassChangeError: Class com.atlassian.jira.rest.client.auth.BasicHttpAuthenticationHandler does not implement the requested interface com.atlassian.jira.rest.client.api.AuthenticationHandler

This is my pom.xml

And this is my code.

import java.io.IOException;
import java.net.URI;

import com.atlassian.jira.rest.client.api.JiraRestClient;
import com.atlassian.jira.rest.client.api.domain.Issue;
import com.atlassian.jira.rest.client.internal.async.AsynchronousJiraRestClientFactory;

public class Dummy {

private String username;
private String password;
private String jiraUrl;
private JiraRestClient restClient;

private Dummy(String username, String password, String jiraUrl) {
this.username = username;
this.password = password;
this.jiraUrl = jiraUrl;
this.restClient = getJiraRestClient();
}

private JiraRestClient getJiraRestClient() {
return new AsynchronousJiraRestClientFactory().createWithBasicHttpAuthentication(getJiraUri(), this.username,
this.password);
}

private URI getJiraUri() {
return URI.create(this.jiraUrl);
}

private Issue getIssue(String issueKey) {
return restClient.getIssueClient().getIssue(issueKey).claim();
}

public static void main(String[] args) throws IOException {
Dummy myJiraClient = new Dummy("username", "password", "http://localhost:8080/secure/WelcomeToJIRA.jspa");
String issueKey = issueKey;
Issue issue = myJiraClient.getIssue(issueKey);
System.out.println(issue.getDescription());

myJiraClient.restClient.close();
}

}

I didn't find any solution for the error, also I don't know where I am wrong. It would be appreciated if someone helps me out where I am wrong. Any help is much appreciated.

Thank you!
