Outdated craftbukkit?

Hello, I am coding a plugin, but when I try to load it, I get a stack trace saying its out of date: http://imgur.com/RjNzBDj
The jar I used in the plugin was: bukkit-1.7.2-R0.3.jar
What do I need to do to fix this?
Thanks in advance.

 

Can I see your main class?

 

Cyber_Pigeon
Did you create any new instance of the Main class anywhere?

 

Yes, I did in every class:

Code:java

Main plugin;

That's not creating a new instance, it's just telling what type of object it is.
This is creating a new instance (and that causes the problem):

Code:java

new Main()

You don't have any other classes that extends JavaPlugin?

 

All my classes extends JavaPlugin

 

Cyber_Pigeon
Only have your Main extends JavaPlugin

 

Gater12 When I do that the method "getConfig" becomes an error.

 

Cyber_Pigeon
You have to get the config from your Main classes instance.
You can do it two ways:
1. CONSTRUCTOR

Code:java

 
/* In your other classes */
private Main plugin;
public YourOtherClassNameHere(Main plugin){
    this.plugin = plugin;
}
plugin.getConfig()
 
/* When creating a new instance of it in your main class */
new YourOtherClassNameHere(this)

2. getInstance()

Code:java

 
/* Make a static variable and then in the onEnable initiate the variable to your plugin */
private static Main instance;
 
public void onEnable(){
    instance = this;
}
 
/* Make your static  method to return your Main class instance */
public static Main getInstance(){
    return instance;
}
 
/* In your other class */
Main.getInstance().getConfig()

 

Gater12 Thanks so much!

Gater12 still has the same stack trace.
