NoClassDefFoundError io/atlassian/fugue/Suppliers JIRA

Question

I am trying to list JIRA projects with the Java SDK following https://www.baeldung.com/jira-rest-api (I could not find another example in Google for this) with the following code:

public static void main(String[] args) {


    JiraRestClient jiraRestClient = getJiraRestClient(URI.create("uri"),"username","token");


    try {
        Iterable<BasicProject> projects =  jiraRestClient.getProjectClient().getAllProjects().get();
        projects.forEach(basicProject -> System.out.println(basicProject.getName()));
    } catch (InterruptedException e) {
        throw new RuntimeException(e);
    } catch (ExecutionException e) {
        throw new RuntimeException(e);
    }
}

private static JiraRestClient getJiraRestClient(URI uri, String username, String password) {
    return new AsynchronousJiraRestClientFactory()
            .createWithBasicHttpAuthentication(uri, username, password);
}

However, it returns this error:

Exception in thread "main" java.lang.NoClassDefFoundError: io/atlassian/fugue/Suppliers

Here are my dependencies:

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

            <version>5.0.0</version>
            <scope>provided</scope>
        </dependency>

Any idea how to run the code correctly?

As mentioned in https://stackoverflow.com/a/75527051/309683, make sure fuge is not marked as provided if you are running the app outside Jira (e.g. not a plugin/extension).

Then this code should work:

package org.example;

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

import java.net.URI;

public class Main {
    private static final String JIRA_URL = "https://your-jira-url.com";
    private static final String JIRA_USERNAME = "your-jira-username";
    private static final String JIRA_PASSWORD = "your-jira-password";

    public static void main(String[] args) throws Exception {
        URI jiraServerUri = new URI(JIRA_URL);
        JiraRestClientFactory factory = new AsynchronousJiraRestClientFactory();
        try (JiraRestClient client = factory.createWithBasicHttpAuthentication(jiraServerUri, JIRA_USERNAME, JIRA_PASSWORD)) {
            Iterable<BasicProject> projects = client.getProjectClient().getAllProjects().claim();
            for (BasicProject project : projects) {
                System.out.println(project.getKey() + ": " + project.getName());
            }
        }
    }
}
