Jira -- Java Rest Client connection issue

[philban]

Hi All,

Hope that someone can help me out here.

In work we are using Jira version 6.17 and I'm trying to connect with it via the java rest client but I seem to be hitting some issues around connect to Jira.

Everytime I run my Java code I get the following error message:

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.AuthenticationHandler
	at com.atlassian.jira.rest.client.internal.jersey.JerseyJiraRestClient.<init>(JerseyJiraRestClient.java:58)
	at com.atlassian.jira.rest.client.internal.jersey.JerseyJiraRestClientFactory.create(JerseyJiraRestClientFactory.java:34)
	at com.atlassian.jira.rest.client.internal.jersey.JerseyJiraRestClientFactory.createWithBasicHttpAuthentication(JerseyJiraRestClientFactory.java:39)
	at com.hw.jira.transitionIssue.main(transitionIssue.java:29)
	at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
	at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57)

	at java.lang.reflect.Method.invoke(Method.java:601)
	at com.intellij.rt.execution.application.AppMain.main(AppMain.java:120)

So here is my Java Code:

package com.hw.jira;

import com.atlassian.jira.rest.client.JiraRestClient;
import com.atlassian.jira.rest.client.NullProgressMonitor;
import com.atlassian.jira.rest.client.domain.*;
import com.atlassian.jira.rest.client.domain.input.FieldInput;
import com.atlassian.jira.rest.client.domain.input.TransitionInput;
import com.atlassian.jira.rest.client.internal.jersey.JerseyJiraRestClientFactory;
import com.google.api.client.http.HttpTransport;

import java.net.URI;
import java.net.URISyntaxException;
import java.util.Arrays;
import java.util.Collection;

import java.util.logging.Handler;
import java.util.logging.Level;
import java.util.logging.LogRecord;
import java.util.logging.Logger;

public class transitionIssue {
    public static void main(String args[]) throws URISyntaxException {
        final JerseyJiraRestClientFactory factory = new JerseyJiraRestClientFactory();
        final URI jiraServerUri = new URI("https://jira.test.com");
        final JiraRestClient restClient = factory.createWithBasicHttpAuthentication(jiraServerUri, "username", "xxxxx");
        final NullProgressMonitor pm = new NullProgressMonitor();
        final Issue issue = restClient.getIssueClient().getIssue("HWTA-374", pm);


        System.out.println(issue);

        // now let's vote for it
        restClient.getIssueClient().vote(issue.getVotesUri(), pm);

        // now let's watch it
        restClient.getIssueClient().watch(issue.getWatchers().getSelf(), pm);

        // now let's start progress on this issue
        final Iterable<Transition> transitions = restClient.getIssueClient().getTransitions(issue.getTransitionsUri(), pm);
        final Transition startProgressTransition = getTransitionByName(transitions, "Start Progress");
        restClient.getIssueClient().transition(issue.getTransitionsUri(), new TransitionInput(startProgressTransition.getId()), pm);

        // and now let's resolve it as Incomplete
        final Transition resolveIssueTransition = getTransitionByName(transitions, "Resolve Issue");
        Collection<FieldInput> fieldInputs = Arrays.asList(new FieldInput("resolution", "Incomplete"));
        final TransitionInput transitionInput = new TransitionInput(resolveIssueTransition.getId(), fieldInputs, Comment.valueOf("My comment"));
        restClient.getIssueClient().transition(issue.getTransitionsUri(), transitionInput, pm);

    }

    private static Transition getTransitionByName(Iterable<Transition> transitions, String transitionName) {
        for (Transition transition : transitions) {
            if (transition.getName().equals(transitionName)) {
                return transition;
            }
        }
        return null;
    }

    public static void enableLogging() {
        Logger logger = Logger.getLogger(HttpTransport.class.getName());
        logger.setLevel(Level.CONFIG);
        logger.addHandler(new Handler() {

            @Override
            public void close() throws SecurityException {
            }

            @Override
            public void flush() {
            }

            @Override
            public void publish(LogRecord record) {
                // default ConsoleHandler will print >= INFO to System.err
                if (record.getLevel().intValue() < Level.INFO.intValue()) {
                    System.out.println(record.getMessage());
                }
            }
        });
    }

}

Hi philban,

I was trying to use the jira-rest-java-client and i'm following the tutorial here: https://ecosystem.atlassian.net/wiki/display/JRJC/Tutorial

...and I'm stuck on the very same issue

at com.atlassian.jira.rest.client.internal.jersey.JerseyJiraRestClient.<init>(JerseyJiraRestClient.java:63)
	at com.atlassian.jira.rest.client.internal.jersey.JerseyJiraRestClientFactory.create(JerseyJiraRestClientFactory.java:34)
	at com.atlassian.jira.rest.client.internal.jersey.JerseyJiraRestClientFactory.createWithBasicHttpAuthentication(JerseyJiraRestClientFactory.java:39)

I think there's some problem on dependancies but I cannot figure out which one...

[Vijay Khacharia]

Here the connection code for JIRA using JRJC version 2.0.0-m26

final AsynchronousJiraRestClientFactory factory = new AsynchronousJiraRestClientFactory();
final JiraRestClient restClient = factory.createWithBasicHttpAuthentication(jiraServerUri, "admin", "admin");

Hope it helps.

Vijay

@Vijay: Can you please share your Pom.xml?

[Saurabh Sharma]

I tried your code but when I run, I get a lot of ClassNotFound kind of errors. I manually downloaded and associated the dependency jars one by one, however I still get the following error: Exception in thread "main" java.lang.NoSuchMethodError: org.apache.http.impl.nio.reactor.DefaultConnectingIOReactor.<init> (Lorg/apache/http/impl/nio/reactor/IOReactorConfig;Ljava/util/concurrent/ThreadFactory;)V at com.atlassian.httpclient.apache.httpcomponents.DefaultHttpClient.<init> (DefaultHttpClient.java:96) at com.atlassian.jira.rest.client.internal.async.AsynchronousHttpClientFactory.createClient(AsynchronousHttpClientFactory.java:53) at com.atlassian.jira.rest.client.internal.async.AsynchronousJiraRestClientFactory.create(AsynchronousJiraRestClientFactory.java:35) at com.atlassian.jira.rest.client.internal.async.AsynchronousJiraRestClientFactory.createWithBasicHttpAuthentication(AsynchronousJiraRestClientFactory.java:42) Can you share your pom.xml? I have maven integrated with ecliipse so I am not able to find Setting.xml. Do I need do something in my setting.xml as well? Please share the correct way to have my code running...

[Vijay Khacharia]

Hi Saurabh,

I have done the few things with JRJC but not using maven. I saw your comment on the other question but was not able to reply till now. I will do that there also so other user see the comment.

May be this link helps to find the dependencies.

http://maven-repository.com/artifact/com.atlassian.jira/jira-rest-java-client-api/2.0.0-m25

Vijay.

[Vijay Khacharia]

I found another answer on the forum where there is some sample code and pom.xml

https://answers.atlassian.com/questions/194406/jira-rest-client-simple-example

[Lorenzo Cavina]

Hi,

I came across this test sample provided with the client source code

https://bitbucket.org/atlassian/jira-rest-java-client/src/75a64c9d81aad7d8bd9beb11e098148407b13cae/test/src/test/java/samples/ExampleCreateIssuesAsynchronous.java?at=master

and changed my code accordingly. Now it works.

Hope this helps.

[Saurabh Sharma]

The link is not opening...

Please provide some alternative.

[philban]

Also are my maven dependancies correct?
