JIRA REST client proper usage

[MB]

How to properly add a JIRA REST client into an already existing JIRA plugin?

I've tried following this tutorial: https://ecosystem.atlassian.net/wiki/display/JRJC/Tutorial

and I've added the following dependency to my pom.xml:

<dependency>
	<groupId>com.atlassian.jira</groupId>
	<artifactId>jira-rest-java-client</artifactId>
	<version>1.1-m02</version>
	<scope>provided</scope>
</dependency>

now, in eclipse (after atlas-mvn eclipse:eclipse) everything shows fine, without any warnings/errors, but at runtime, this line:

JerseyJiraRestClientFactory f = new JerseyJiraRestClientFactory();

gives me an exception like:

java.lang.NoClassDefFoundError "com/atlassian/jira/rest/client/internal/jersey/JerseyJiraRestClientFactory"

Does anyone know how to add/use jira-rest-java-client properly to an already existing plugin?

See my answer here for a working example - https://answers.atlassian.com/questions/194331/can-anyone-provide-a-simple-example-of-jira-rest-java-client-jrjc-plugin-code/196799

Excellent answer!

Thanks a lot for providing it! :)

Put the scope as compile. JRJC is not part of JIRA and so you will need those classes in the plugins classpath.

You're the man Jobin!!! :)))

It worked like a charm :) But.. :)

Now, I'm getting the exception "java.lang.NoClassDefFoundError: Could not initialize class org.apache.commons.httpclient.HttpState" at line:

jc = f.createWithBasicHttpAuthentication(new URI("http://localhost:8080"), "admin", "admin");

the test code I tried to execute was something simple:

private void blah() {
	JerseyJiraRestClientFactory f = new JerseyJiraRestClientFactory();
	JiraRestClient jc;
	try {
		jc = f.createWithBasicHttpAuthentication(new URI("http://localhost:8080"), "admin", "admin");

		SearchResult r = jc.getSearchClient().searchJql("type = Bug ORDER BY RANK ASC", null);

		for (BasicIssue basicIssue : r.getIssues()) {
			com.atlassian.jira.rest.client.domain.Issue issue = jc.getIssueClient().getIssue(basicIssue.getKey(), null);
			System.out.println("Bug: " + issue.getKey() + " " + issue.getSummary());
			for (IssueLink issueLink : issue.getIssueLinks()) {
				com.atlassian.jira.rest.client.domain.Issue issueL = jc.getIssueClient().getIssue((issueLink).getTargetIssueKey(), null);
				System.out.println(issueLink.getIssueLinkType().getDescription() + ": " + issueL.getKey() + " " + issueL.getSummary() + " " + issueL.getFieldByName("Story Points").getValue());
			}
		}
	} catch (URISyntaxException e) {
		// TODO
	}
}

I'll accept your answer, because it solved my initial question though :)

Thanks once again! :)

P.S. Does anyone know how to notify author of that doc page to update the page with <scope>compile</scope>

It is the same thing. You are missing another class at runtime. I guess apache httpclient this time. I wonder why it is not pulled in by JRJC dependency but see if you can fix it by adding it in your pom.xml.

https://ecosystem.atlassian.net/wiki/display/JRJC/Project+Dependencies shows the dependencies for JRJC. They should normally be pulled in by JRJC.

I was afraid you were going to say that :)

Anyway, thanks a lot again!

Use jira-rest-java-client-api instead of jira-rest-java-client.

I too faced the same issue.

Just a curious question. Why do you need the REST client when the add on already provides you access to most of the API?

[MB]

I'm not sure I quite understand your question, but I need to implement a plugin, which will serve as a kind of a proxy for the gadget's REST calls (retrieving information from another JIRA instance), so at one point my plugin needs to act as a REST service provider (towards the gadget) and at another point (towards another JIRA instance) it needs to act as a REST client, right?

[Timothy]

Yea. That is one way to do it. But you can always just use a Jersey client to call the other REST instead of using the whole JIRA REST client.
