Encapsulation from main class

Hello,
I want to use data from the Plugin.YML file outside of the main class. To achieve this, I'm using encapsulation.
Main class:

Code:

    private PluginDescriptionFile pdf;

    public PluginDescriptionFile getPDF(){
        return this.getDescription();
    }

Command class:

Code:

public class Version implements CommandExecutor{
  
    EndWars pdf = new EndWars();
  
    @Override
    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
        if(cmd.getName().equalsIgnoreCase("ewversion")){
            sender.sendMessage("You're running version: " + pdf.getPDF().getVersion());
        }
        return true;
    }

}

When the plugin loads, the server throws the error:

Code:

[14:43:32 ERROR]: Error occurred while enabling EndWars v0.1-DEV (Is it up to date?)
java.lang.IllegalArgumentException: Plugin already initialized!

Line 12 in Version.class is causing the error, which is:

Code:

EndWars pdf = new EndWars();

To my understanding, this line is initializing the main class a second time which is probably confusing the server about which class is the main class.

Does anyone know how to access a variable from the main class?
AFAIK the PluginDescriptionFile method file is only available in the main class.

Sorry for any grammar mistakes, English is not my native language.
