Solved Getting plugin version returns me IllegalStateException

So I was developing a plugin using SpigotAPI, and I wanted to include a command to view the version of the plugin. However, while doing so, the command is throwing a IllegalStateException: Initital initialization

Code:java

 
public class GetVersion implements CommandExecutor {
    @Override
    public boolean onCommand(CommandSender player, Command command, String s, String[] args) {
        PluginDescriptionFile descriptionFile = new Main().getDescription();
        if (command.getName().equalsIgnoreCase("btversion")){
            player.sendMessage(ChatColor.YELLOW + "You are running [Plugin name here] " + ChatColor.GREEN + descriptionFile.getVersion());
            return true;
        }else{
            return false;
        }
    }
}
 

What is wrong with the code?

 

Thanks a lot! It helped!
