Plugin help!

There's a few things wrong with the code provided - nothing to panic about though, I have made similar mistakes beforehand:

1. Your plugin.yml isn't formatted properly. It should look like this:
name: RFPvpHelper
main: me.Pixelizedgaming.ParkourPlugin
version: 1.0.5
commands:
revenge:
description: Let your killer feel your wrath!
permission: RedFactionsPvpHelper.revenge
usage: /<command>
2. You may want to include a != null check for player.getKiller() in case it returns null, so just add this snippet of code and your plugin should have fewer exceptions thrown:
if (player.getKiller() != null) {
Player p = player.getKiller();
player.sendMessage(ChatColor.GOLD +"Successfully punished" + ChatColor.GRAY + p.getDisplayName());

// All of your other code here

p.sendMessage(ChatColor.DARK_PURPLE+ "Thou have been punished!");
} else {
player.sendMessage(ChatColor.DARK_RED + "You don't have anyone to punish!");
}

I mean that when i look in the server plugin list, the plugin isn't there. I have a plugin.yml,
here.


and here is the PlayerListener class mentioned in the code above.

package me.Pixelizedgaming;

import java.util.Random;

import org.bukkit.ChatColor;
import org.bukkit.Material;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;

import org.bukkit.event.player.PlayerItemConsumeEvent;
import org.bukkit.event.player.PlayerJoinEvent;
import org.bukkit.event.player.PlayerRespawnEvent;
import org.bukkit.inventory.ItemStack;

import org.bukkit.potion.PotionEffect;
import org.bukkit.potion.PotionEffectType;











public class PlayerListener implements Listener{
public PlayerListener(ParkourPlugin plugin){
plugin.getServer().getPluginManager().registerEvents(this,plugin);


}
@EventHandler
public void Teleport(PlayerRespawnEvent event){
Player player = event.getPlayer();
player.chat("I died! Yay!");
player.performCommand("spawn");
Player h = player.getKiller();
h.getInventory().addItem(new ItemStack(Material.SPONGE, 1));
h.sendMessage(ChatColor.DARK_AQUA + "Congrats on that Kill! Here's a piece of Sponge! Exchange it for blaze rods in " + ChatColor.RED +"/warp shop.");


}
@EventHandler
public void Teleport1(PlayerItemConsumeEvent event){
Player player = event.getPlayer();
Random random = new Random();
double e = random.nextInt(11);
double g = player.getHealth();
player.setHealth(g + e);

player.sendMessage(ChatColor.GRAY + "Yum! You Gained " + ChatColor.AQUA + e + ChatColor.GRAY+ " Health!");

}
@EventHandler
public void GG(PlayerJoinEvent event){
Player player = event.getPlayer();
player.addPotionEffect(new PotionEffect(PotionEffectType.DAMAGE_RESISTANCE, 20, 3));


}
}

There could be a bunch of issues.

- Did you include a plugin.yml?
- Is the main variable set in the plugin.yml?
- Are you checking for runtime errors from stdout/console?

Describe what you mean by "didn't show up".
