IllegalArgumentException

Hi.
I have a problem with my separate CommandExecutor class
I use this code for loading an Integer from the config

Code:

private VoteEarn VE = new VoteEarn();
Integer curr = VE.getConfig().getInt("user."+ sender.getName() + ".curr");

In the main class it workes perfectly.
Error Code:

Code:

[SCHWERWIEGEND] null
org.bukkit.command.CommandException: Unhandled exception executing command 'vote
' in plugin VoteEarn v0.1
Caused by: java.lang.IllegalArgumentException: File cannot be null

 

You're probably trying to do this before the plugin has been fully initialized. You can't access the config until onEnable is called.

Edit: Actually, this is probably because you're creating a new instance of your main class. You can't do that, you need to use the real instance of your plugin class.

 

And how shoud I do that?
I don't want to put the full code in one Class.

 

its simple, just dont create a new version of your plugin.

youre doing

Code:

private VoteEarn VE = new VoteEarn();
Integer curr = VE.getConfig().getInt("user."+ sender.getName() + ".curr");

just do,

Code:

Integer cur = getConfig().getInt("user."+ sender.getName() + ".curr");
 
//or if youre NOT inside of your main class file:
 
Integer cur = yourplugininstance.getConfig().getInt("user."+ sender.getName() + ".curr");

If youre still getting a null exception, then that means youre setting your config before onEnable AKA as a declared class variable of your main class, or the result OF one of said variables.

 

And how I can get my plugin instance?

 

you find a way to pass it from your main class file into the constructor of the new object, then store it in a variable there.

 

Sry but I'm not good in developing.
Can you pls give me one example?

Edit: Can I use this:

Code:

getCommand("vote").setExecutor(CommandListener);

 

... Do do you know what constructors are? or parameters?

If not, no offense, then you should go back to learning java before developing plugins :x

 

I konw that I have to learn java, but I need this plugin.
And this config is the only think that is missing

 

watch this and this

Using both constructors and parameters, you can create a constructor with a parameter of your plugin. Pass your plugin into the constructor via a parameter, and store it locally, to use from there.

 

Thank you very much.
You helped me a lot
