File cannot be null?

Hey. Please help, ever since I added a list to the config, I got the following stacktrace:

My stacktrace:

Code:java

[16:05:24 ERROR]: Could not load 'plugins\Crates.jar' in folder 'plugins'
org.bukkit.plugin.InvalidPluginException: java.lang.IllegalArgumentException: Fi
le cannot be null

My code:

Code:java

public void loadConfig(){
 
    FileConfiguration config = this.getConfig();
 
    List<String> donorchest1 = config.getStringList("crates.donorchest1.rewards");
    List<String> donorchest = config.getStringList("crates.donorchest.rewards");
    List<String> randomchest = config.getStringList("crates.randomchest.rewards");
    donorchest1.add("EMERALD_ORE");
    donorchest.add("EMERALD_ORE");
    randomchest.add("EMERALD_ORE");
 
    config.addDefault("crates.donorchest1.Z", 0);
    config.addDefault("crates.donorchest1.Y", 50);
    config.addDefault("crates.donorchest1.X", 0);
    config.addDefault("crates.donorchest1.world", "world");
    config.addDefault("crates.donorchest1.keyname", "key1");
    config.addDefault("crates.donorchest1.rewards", donorchest1);
 
    config.addDefault("crates.donorchest.Z", 1);
    config.addDefault("crates.donorchest.Y", 50);
    config.addDefault("crates.donorchest.X", 1);
    config.addDefault("crates.donorchest.world", "world");
    config.addDefault("crates.donorchest.keyname", "key1");
    config.addDefault("crates.donorchest.rewards", donorchest);
 
    config.addDefault("crates.randomchest.Z", 2);
    config.addDefault("crates.randomchest.Y", 50);
    config.addDefault("crates.randomchest.X", 2);
    config.addDefault("crates.randomchest.world", "world");
    config.addDefault("crates.randomchest.keyname", "key1");
    config.addDefault("crates.randomchest.rewards", randomchest);
 
 
 
    this.getConfig().options().copyDefaults(true); // NOTE: You do not have to use "plugin." if the class extends the java plugin
    this.saveConfig();
}
 

 

Please post the whole stacktrace...

Sorry.

 

There is something wrong with your config. Looks like you are accessing it too early or something like that. I bet you are using it wrong or on a constructor. Please post the whole main class.

 

Don't extend JavaPlugin in more than one class and don't set any fields using "getConfig()" in your main class like so:

Code:java

public class MyPlugin extends JavaPlugin {
 
    private final String myString = getConfig().getString("doh"); // Bad!
 
}
