How do i need to do it then?

 

Like this in the onEnable:

ConfigurationManager config = new ConfigurationManager(this);

?

 

Add this to your main:

Code:

private static Main instance;

public Main() {
    instance = this;
}

public static Main getInstance() {
    return this;
}

Use Main.getInstance() to get "this" in a different class.

 

Yes and then?
How do i get the configurationmanager class?

 

I think you can only get "this" from the main class.

EDIT:

Your main throws a NoSuchMethodException and I think this has something to do with it. Can you explain what it's supposed to do?

 

I want a custom config in a diffrent class then the Main class for a organized Main class

 

Try taking that out then add what I gave you earlier. Replace "main.getDataFolder()" in ConfigManager with "Main.getInstance().getDataFolder()", then get rid of ConfigurationManager(Main main) in ConfigManager and main(ConfigurationManager config) in Main.

 

It gives me a error at: return this;
Error: Cannot use this in a static context

 

But then i can't get the Main class instance in the ConfigurationManager

 

Doesn't work i get this error in the console:

Error (open) Error (close)

This is line 15 of ConfigurationManager class: public File Test = new File(main.getDataFolder() + "/Test.yml");

And line 17 in Main class is this: ConfigurationManager config = new ConfigurationManager(this);

 

And how do i do that?

 

@timtower I have now created this: File dataFolder = ((Main)Bukkit.getPluginManager().getPlugin("Test")).getDataFolder();

And that works. But is there a simpler way to get the DataFolder outside the main?

 

You mean like this: Main main = new Main();?
in the ConfigurationManager class

 

Already 2 years but i learned it out of my self so i don't know the tips and tricks in Java

@timtower i only need the getDataFolder in the ConfigurationManager class, but how?

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

 

Which contructor?

@timtower Can you give me a example?

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

 

It doesn't work. It gives me errors in this whole thing :/

 

This is the error on "this.main = main": main cannot be resolved or is not a field
And this is the error on "this.Test = new File(this.Test, main.getDataFolder());": The constructor File(File, File) is undefined
