    @Override
    public void onDisable(){
        PluginDescriptionFile pdfFile = this.getDescription();
        this.logger.info(pdfFile.getName() +"version" + pdfFile.getVersion() + "is now disabled");
        this.saveDefaultConfig();
        }
   
   
   
    @Override
    public void onEnable(){
        PluginDescriptionFile pdfFile = this.getDescription();
        this.logger.info(pdfFile.getName() +"version" + pdfFile.getVersion() + "is now enabled");
        getServer().getPluginManager().registerEvents(this, this);
       
    }
    @EventHandler
    public void onJoin(PlayerJoinEvent event)
    {
    event.setJoinMessage(ChatColor + event.getPlayer().getName() +  welcomeMessage);
    }
       
       
    }

You're defining config before it's instantiated (i think is the word)

 

Sorry i do not follow

 

Code:

public String ChatColor = getConfig().getString("color.path");

You told eclipse this before the server is even loaded

 

ah

but when i move it it doesnt work

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

You can define it, but only initialize it when you know the server is plugin loaded

 

i think i understand
