Need help with config (I think)

I currently have a listener running for when players log in, it checks if they've been on the server before, and if they haven't make a data slot for them (I am storing the data for them in a yml file). Whenever I log on to test, It throws this error:

Code:

[21:26:49] [Server thread/ERROR]: Cannot load configuration from stream
org.bukkit.configuration.InvalidConfigurationException: expected '<document start>', but found Scalar

[21:28:32] [Server thread/INFO]: Unknown command. Type "help" for help.

Here's the code of the Listener:

Code:java

private class JoinListener implements Listener {
 
@EventHandler (priority = EventPriority.HIGH)
public void onJoin (PlayerJoinEvent e){
Player player = e.getPlayer();
if (!playedBefore(player) == true){
int amountToAdd = getConfig().getInt("default-lives");
addLives(amountToAdd, player);
}
}
}

Code for the method "playedBefore":

Code:java

public boolean playedBefore (Player playerName){
Player player = playerName;
if (getConfig().contains("data." + player)){
return true;
}
return false;
}

Here's the code for the method addLives:

Code:java

public void addLives(int amount, Player playerName){
Player player = playerName;
int before = getConfig().getInt("data." + player);
int after = before + amount;
this.getConfig().set("data." + player, after);
}

And here's the default config:

Code:

#Amount of lives a player starts with
default-lives:5
 
#Max amount of lives
max-lives:10
 
#Does it say the player's lives over his head?
display-lives-over-head: true
 
data:
    # (PlayerName) : (Lives they have)

Thanks in advance for the help!

Join listener does not extend JavaPlugin 0_O
You should make a reference to a main class. There are several ways to do this I will show you mine:
1. Add a line to your Main class that is:

Code:java

Main plugin;

2. Now add this to your onEnable. This will define the variable we just created:

Code:java

plugin = this;

3. Add this method to the class. The name of it doesn't matter, you can use getInstance, getPlugin, or anything!

Code:java

public static Main getPlugin() {
return plugin;
}

4. Now you can reference the main class by doing this:

Code:java

Main.getPlugin()
// If you want to get the config
Main.getPlugin().getConfig()

Then we're done! You can now use methods from JavaPlugin in other classes!
Optional:
If you want to just do Main.getConfig() we can!
Make a method called getConfig()

Code:java

public static FileConfiguration getConfig() {
  return plugin.getConfig();
}

 

It's in my main class. Sorry, I should have been more clear about that

 

Have you parsed the YAML doc? This is a good place.

 

what's that mean?
