I am trying to connect to JIRA using jira-java-client(provided by atlassian)

[Ashish_Ranjan]

CODE DETAILS: Here is my build.gradle file(app level)

apply plugin: 'com.android.application'

android {
    compileSdkVersion 29
    buildToolsVersion "29.0.2"
    defaultConfig {
        applicationId "com.example.appautomation"
        minSdkVersion 15
        targetSdkVersion 29
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'androidx.appcompat:appcompat:1.1.0'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test.ext:junit:1.1.1'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
    testImplementation group: 'junit', name: 'junit', version: '4.12'
    testImplementation group: 'io.appium', name: 'java-client', version: '6.1.0'
    testImplementation group: 'org.testng', name: 'testng', version: '6.14.3'

    // https://mvnrepository.com/artifact/com.atlassian.jira/jira-rest-java-client-core
    implementation group: 'com.atlassian.jira', name: 'jira-rest-java-client-core', version: '5.1.1-e0dd194'
    // https://mvnrepository.com/artifact/com.atlassian.jira/jira-rest-java-client-api
    implementation group: 'com.atlassian.jira', name: 'jira-rest-java-client-api', version: '5.1.1-e0dd194'

    // https://mvnrepository.com/artifact/io.atlassian.fugue/fugue
    compileOnly group: 'io.atlassian.fugue', name: 'fugue', version: '4.7.2'

    // https://mvnrepository.com/artifact/org.slf4j/slf4j-simple

    implementation group: 'com.atlassian.httpclient', name: 'atlassian-httpclient-api', version: '0.23.2'

}

And this is my Java code for connection and fetching an issue

import com.atlassian.jira.rest.client.api.JiraRestClient;
import com.atlassian.jira.rest.client.internal.async.AsynchronousJiraRestClientFactory;
import java.net.URI;
import java.net.URISyntaxException;

import io.atlassian.util.concurrent.Promise;
import utils.LogUtils;

public class JiraIntegration {
    private final String EMAIL = "rahul.vig@jifflenow.com";
    private final String USERNAME = EMAIL;
    private final String PASSWORD = "DHPfuy5LaNH9uijTeeqO203E";

    public void jiraConnectionSetup() throws URISyntaxException {
        try {
            final URI jiraServerURI = new URI("https://jirajifflenow.atlassian.net/");
            final JiraRestClient jiraRestClient = new AsynchronousJiraRestClientFactory().createWithBasicHttpAuthentication(jiraServerURI, USERNAME, PASSWORD);
            Promise issuePromise = jiraRestClient.getIssueClient().getIssue("MOBILE-2773");
            LogUtils.setInfo("Here is you Issue" + issuePromise);
        } catch (ExceptionInInitializerError e) {
            LogUtils.setError("Error happened " + e.getCause());
            e.printStackTrace();
        }

    }
}

 I have looked in for this issue but didn't got any promising result.

Let me know what I am missing the implementation.
