Plugin problem: Classnotfound exception...

I know it's a common problem, and I'm still fairly new to bukkit plugin dev, but I can't for the life of me figure this one out! I feel like everything's working fine. Then again, a lot of this was guessing what to do until the red squiggly lines went away in eclipse, because I couldn't find any tutorials on something similar to this.

Basically, what I'm trying to do is: When a player dies, it gets the killer, and adds one to their number in the hashmap, which means their kill count. Later on, at certain intervals, they will get rewards, etc.

Here's my error log:

Here's my plugin.yml:

Code:

version: 1.0
description: Counts kills, and does other PVP related things. Made for the Rangers PVP server!

killcounts.topcount:

(I intend to use those permissions later in the code.)

Aanndd here's my source:

Show Spoiler Hide Spoiler

Code:

package me.toughenough6.KillCounts;
 
import java.util.HashMap;
import java.util.Map;
 
 
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.entity.PlayerDeathEvent;
import org.bukkit.plugin.java.JavaPlugin;
 
 
public class KillCounts extends JavaPlugin{
 
public int kills = 0;
public Map<Player, Integer> hashmap = new HashMap<Player, Integer>();
@EventHandler
public void onEntityDeath(final PlayerDeathEvent event){
if(event.getEntity() instanceof Player){
Player deadplayer = (Player) event.getEntity();
Player killerplayer = deadplayer.getKiller();
if(killerplayer == null) {
return;
} else {
killerplayer.sendMessage("You seem to have killed " + deadplayer + ". Congrats.");
hashmap.put(killerplayer, +1);
deadplayer.sendMessage("You were killed by " + killerplayer + ". That sucks.");
}
}
}
}

So, if anyone has any idea how to fix this, I would greatly appreciate it. Maybe even giving me some tips on where to go with this plugin? Right now it's going to be a killcounter with rewards given at certain intervals, and the ability to check your own/others kill counts.
Thanks!

Also, I've already looked here, so don't send me there.

 

Bukkit can't find your KillCounts class.

Are you sure you dealt with all compilation errors? Are you sure you include KillCounts
when you create the .jar file?

Also, don’t store Players in HashMaps, store their names instead.
Package names begin with a lowercase letter.
Your plugin needs to have a onEnable() method that registers the events.
hashmap in not very descriptive.
