Problem with's config

What is bad in this code ?

World world = Bukkit.getWorld(getConfig().getString("SGF.Lobby.world"));

 

Nothing. What is the error? Is it in the main class?

 

Yea
at teams.Main.onCommand(Main.java:102) ~[?:?]

 

Nothing, assuming there is a) A string at "SGF.Lobby.world" and b) There is a world with the name given by the string at "SGF.Lobby.world"

 

Caused by: java.lang.IllegalArgumentException: Name cannot be null

 

Let me introduce you to a very good method of debugging such errors.

Above where you have your world variable, put this code

Code:

Bukkit.broadcastMessage(getConfig().getString("SGF.Lobby.world"));

If it prints out null, then there's your problem, you don't have that string defined in your config.
If it prints out a string, then check there is a world with that name
The former is more likely in this case

 

Ohhh
I was stupid :_:
I used getConfig
I must use : cfg

Now it's working !
