How to create an issue in JIRA using java rest api

[anuj chaurasia]

I have checked almost every link but could not find the proper solution for it.
I need to create an issue in JIRA using java rest api.
Code :-

import java.io.IOException;
import java.net.URI;
import java.net.URISyntaxException;
import org.codehaus.jettison.json.JSONException;
import com.atlassian.jira.rest.client.api.JiraRestClient;
import com.atlassian.jira.rest.client.api.domain.BasicProject;
import com.atlassian.jira.rest.client.api.domain.Issue;
import com.atlassian.jira.rest.client.internal.ServerVersionConstants;
import com.atlassian.jira.rest.client.internal.async.AsynchronousJiraRestClientFactor;

public class TestingRestAPI {
private static URI jiraServerUri =
URI.create("https://vgsvdgteam.jira.com/rest/api/2/project");
public static void main(String[] args) throws URISyntaxException,
JSONException, IOException {
final AsynchronousJiraRestClientFactory factory = new
AsynchronousJiraRestClientFactory();
final JiraRestClient restClient = factory.createWithBasicHttpAuthentication(jiraServerUri, "liasia","cooki123!!");
try {
final int buildNumber = restClient.getMetadataClient().getServerInfo().claim().getBuildNumber();
System.out.println("---------------------------------"+buildNumber);
// first let's get and print all visible projects (only jira4.3+)
System.out.println("Print all print all visible projects:");
if (buildNumber >= ServerVersionConstants.BN_JIRA_6) {
final Iterable<BasicProject> allProjects = restClient.getProjectClient().getAllProjects().claim();
for (BasicProject project : allProjects) {
System.out.println(project);
}
}
// then print one issue details
System.out.println("Print issue TST-63239");
final Issue issue = restClient.getIssueClient().getIssue("TST-63239").claim();
System.out.println(issue);
}
finally {
restClient.close();
}
}
}

Dependency added in pom.xml :-

<dependency>
<groupId>com.atlassian.jira</groupId>
<artifactId>jira-rest-java-client-api</artifactId>
<version>2.0.0-m25</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>com.atlassian.jira</groupId>
<artifactId>jira-rest-java-client-core</artifactId>
<version>2.0.0-m25</version>
<scope>provided</scope>
</dependency>

Exception getting :-

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

After checking the exception it seems the claim() function of Serverinfo class has the problem.
Or the URL has any issue ?
Can some help me to overcome this issue or any useful link?

Have you tested a simple REST create call?  Instead of messing around with whatever libraries this code might be coming from, just a single "curl" to ensure you've got the basics right?
