My Plugin code Is Not Working..

Here is the code.... It won't work - when I do /plugins it shows no plugins

The code is supposed to give a player a diamond pickaxe when they type /bb
I will also give my config.xml file.

BB.java Is Below.

package com.enjin.mlgplugins333.BB;

import org.bukkit.Material;
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import org.bukkit.inventory.ItemStack;
import org.bukkit.plugin.java.JavaPlugin;

public class BB extends JavaPlugin {




@Override
public void onEnable() {
getLogger().info("BB Has Been Enabled.");
}

@Override
public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
if(cmd.getName().equalsIgnoreCase("BB")) {
Player.sendMessage("Giving Diamond Pickaxe.");
ItemStack pick = new ItemStack(Material.DIAMOND_PICKAXE);
Player.getInventory().addItem(pick);
return true;

}



return false;

}





@Override
public void onDisable() {
getLogger().info("BB Has Been Disabled.");

}
