Get resource version
Example
You will be able to check if the version of the plugin is the same as the version on the site. You can then warn users to update the plugin.
public class VersionChecker implements Listener {
​
	private final String URL_API = "https://groupez.dev/api/v1/resource/version/%s";
	private final String URL_RESOURCE = "https://groupez.dev/resources/%s";

	private final int pluginID;
	private boolean useLastVersion = false;

	 * Class constructor
	 * 
	 * @param plugin
	 * @param pluginID

	public VersionChecker(Plugin plugin, int pluginID) {
		super();
		this.plugin = plugin;
		this.pluginID = pluginID;
	}
​
	/**
	 * Allows to check if the plugin version is up to date.
	 */
	public void useLastVersion() {
​
		Bukkit.getPluginManager().registerEvents(this, this.plugin); // Register
																		// event
​
		String pluginVersion = plugin.getDescription().getVersion();
		AtomicBoolean atomicBoolean = new AtomicBoolean();
		this.getVersion(version -> {
​
			long ver = Long.valueOf(version.replace(".", ""));
			long plVersion = Long.valueOf(pluginVersion.replace(".", ""));
			atomicBoolean.set(plVersion >= ver);
			this.useLastVersion = atomicBoolean.get();
			if (atomicBoolean.get())
				Logger.info("No update available.");
			else {
				Logger.info("New update available. Your version: " + pluginVersion + ", latest version: " + version);
				Logger.info("Download plugin here: " + String.format(URL_RESOURCE, this.pluginID));
