Plugin/<pluginname> Folder

I followed some guides on how to create config files for each player, but I got stuck. I'm trying to create a new file at the location with

Code:

public static YamlConfiguration loadPlayerConfig(String playername){
        File f = new File(pluginPath,playername + ".yml");
        if(!(f.exists() && !f.isDirectory())){
            Log.message("Creating file for "+playername);
            try {
                f.createNewFile();
            } catch (IOException e) {
                Log.alert(playername+"'s file could not be created!");
                Log.debug(e.toString());
            }
        }
        YamlConfiguration yc = YamlConfiguration.loadConfiguration(f);
        return yc;
    }

pluginPath is set to getDataFolder().getAbsolutePath() in the onEnable

I'm getting java.ioi.IOException: The system cannot find the path specified
and my plugins folder does not have a <pluginname> folder, do I have to create it manually?

You don't need to call getAbsolutePath().

Call getDataFolder().mkdir() in your onEnable() to ensure it's creation.

 

If I want to create a file inside my plugin's folder, I simply do this.

Code:java

String path = "plugins/MinecraftRP/config.yml";
File file = new File(path);
if (!file.exists()) {
FileConfiguration fileConfig = new YamlConfiguration();
try{
fileConfig.save(file);
}catch(IOException ex) {
//output some error message
}
}

Where MinecraftRP is the name of my plugin

• Plugin#getDataFolder() encapsulates plugins/pluginName
• You could just use Bukkit API for default config file...
• In my opinion, it is bad practice to use '/', sometimes File separator can be a different character. Use System.getProperty("file.separator") or File.Separator. Usually that is fine though.

Can I suggest using this resource? It helps make configuration management much easier.

 

Ok, well I use this code for much more than just config files.

Thanks for the tips.

 

I used mkdir and I can create the file in the folder, but I still get an error in bukkit?

I can find my player file in plugins/pluginname/players/Shadow_Ninjax.yml
but why am I getting this error? Anyone know?
It says Illegal State Exception
