Can't get my plugin to start

I'm new to developing plugins for Bukkit and I can't seem to get it to start. I'll include the error i get in the server output, and the Main class source.

Server error


MainServer.java source :

Code:

package com.bukkit.hawksprite.MainServer;

import java.io.*;
import java.util.HashMap;

import org.bukkit.Server;
import org.bukkit.entity.Player;
import org.bukkit.event.Event;
import org.bukkit.event.Event.Priority;
import org.bukkit.event.Listener;
import org.bukkit.plugin.PluginDescriptionFile;
import org.bukkit.plugin.PluginLoader;
import org.bukkit.plugin.PluginManager;
import org.bukkit.plugin.java.JavaPlugin;

public class MainServer extends JavaPlugin {
    public MainServer(PluginLoader pluginLoader, Server instance,
            PluginDescriptionFile desc, File folder, File plugin,
            ClassLoader cLoader) {
        super(pluginLoader, instance, desc, folder, plugin, cLoader);
        // TODO Auto-generated constructor stub
    }

    private final MainServerPlayerListener playerListener = new MainServerPlayerListener(this);
    private final MainServerBlockListener blockListener = new MainServerBlockListener(this);
    private final HashMap<Player, Boolean> debugees = new HashMap<Player, Boolean>();

    public void onEnable() {
        // TODO: Place any custom enable code here including the registration of any events

        // Register our events
        PluginManager pm = getServer().getPluginManager();

        pm.registerEvent(Event.Type.BLOCK_PLACED, blockListener, Priority.Normal, this);

        // EXAMPLE: Custom code, here we just output some info so we can check all is well
        PluginDescriptionFile pdfFile = this.getDescription();
        System.out.println( pdfFile.getName() + " version " + pdfFile.getVersion() + " is enabled!" );
    }
    public void onDisable() {
        // TODO: Place any custom disable code here

        // NOTE: All registered events are automatically unregistered when a plugin is disabled

        // EXAMPLE: Custom code, here we just output some info so we can check all is well
        System.out.println("Goodbye world!");
    }
    public boolean isDebugging(final Player player) {
        if (debugees.containsKey(player)) {
            return debugees.get(player);
        } else {
            return false;
        }
    }

    public void setDebugging(final Player player, final boolean value) {
        debugees.put(player, value);
    }
}

 

Don't use a constructor.

Also, make sure your plugin.yml is formatted correctly. If you are unsure, post it here.

 

Whoa, way outdated stuff you've used. You might want to take a look at http://forums.bukkit.org/threads/bukkit-updates-tutorial.7093/

 

I'm not 100% sure what you mean by constructure (I do must of my codeing in C#). I'll post my plugin.yml.

Thanks for the links i'll make a note to watch the tutorial.

Code:

name: MainServer
main: com.bukkit.hawksprite.MainServer.MainServer
version: 1

 

C# (like C++) has constructors as well. Its what is called when you create an instance of a class or struct.

In your above code it is this:

Code:

    public MainServer(PluginLoader pluginLoader, Server instance,
            PluginDescriptionFile desc, File folder, File plugin,
            ClassLoader cLoader) {
        super(pluginLoader, instance, desc, folder, plugin, cLoader);
        // TODO Auto-generated constructor stub
    }

take this out.

 

I had never refereed to them as constructors before, but i know what your talking about now. I got it running after taking that snippet out and watching that you tube video.

 

ummm, he can still have a constructor, as they can be useful to initialize the plugin data variables to a known good state until enable is called, it just can't take any parameters

 

I have always read they shouldn't be used. Never employed them myself since it wasn't needed.
