Error when loading plugin using Jedis - Minecraft server - plugins

Question

Just wondering what's causing this. I have no idea!
I am trying to make a queue plugin. I am using paper spigot. Please ignore all the holes in my plugins code as I'm simply testing it at the moment. If you have anything that you think I should change however I'd be glad to here it. Here is my error message spat out by the terminal.

And here's my code:
package com.Package;
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import org.bukkit.event.player.PlayerJoinEvent;
import org.bukkit.plugin.java.JavaPlugin;
import org.bukkit.scheduler.BukkitScheduler;
import com.google.common.io.ByteArrayDataOutput;
import com.google.common.io.ByteStreams;
import redis.clients.jedis.Jedis;
import java.util.ArrayList;
import java.util.logging.Logger;
public class AnarchyQueue extends JavaPlugin {
//list of players in queue
private ArrayList<Player> players = new ArrayList<Player>();
//jedis object to communicate with other server
private Jedis jedis = new Jedis("localhost");
private int playerCount = 0;
static int maxPlayerCount = 10;
#Override
public void onEnable() {
onEnablePri();
}
#Override
public void onDisable() {
onDisablePri();
}
public void onPlayerJoin(PlayerJoinEvent event)
{
onPlayerJoinPri(event);
}
#Override
public boolean onCommand(CommandSender sender, Command command, String label, String[] args) {
onCommandPri(sender,command,label,args);
return true;
}
//--------------------private methods--------------------
private void onEnablePri() {
log("Server test: "+jedis.ping(),1);
BukkitScheduler scheduler = getServer().getScheduler();
scheduler.scheduleSyncRepeatingTask(this, new Runnable() {
#Override
public void run() {
runPri();
}
}, 0L, 10L);;
}
private void runPri() {
try {
playerCount=Integer.parseInt(jedis.get("anarchy-player-count"));
} catch (Exception e) {
log("Player count get failed",1);
}
if(playerCount<maxPlayerCount)
{
ByteArrayDataOutput out = ByteStreams.newDataOutput();
out.writeUTF("Connect");
out.writeUTF("anarchy");
players.get(0).sendPluginMessage(this, "BungeeCord", out.toByteArray());
players.remove(0);
}
}
private void onDisablePri() {
//disable code
}
private void onPlayerJoinPri(PlayerJoinEvent event)
{
players.add(event.getPlayer());
}
private void onCommandPri(CommandSender sender, Command command, String label, String[] args) {
if(command.getName().equalsIgnoreCase("setmaxplayercount"))
{
jedis.set("anarchy-player-count",args[0]);
}
/*if (command.getName().equalsIgnoreCase("players")) {
if (!(sender instanceof Player)) {
sender.sendMessage("You must be in game!");
}
else {
getCount();
}
} */
}
//private void getCount() {
//}
private void log(String str, int i)
{
if(i==0)
{
Logger.getLogger("Minecraft").info(str);
}
else
{
if(i!=1)
{
System.out.println("NUMBER NOT RECOGNISED: ");
}
System.out.println(str);
}
}
}
And finally here's my plugin.yml (in case this is wrong)
main: com.Package.AnarchyQueue
name: AnarchyQueue
version: '1.0'
description: The queue plugin for Ed_Silver's anarchy server.
load: postworld
author: Ed_Silver
prefix: AnarchyQueue
commands:
setmaxplayercount:
description: Sets max player count
usage: /setmaxplayercount [int]
I saw a post that spoke about needing to add a dependency using a pom.xml but I don't know if that applies to me.
Thanks in advance,
If you need anything just ask,
Edward

Answer 1

You are trying to import redis.clients.jedis.Jedis; but Minecraft cant find Jedis, you have to add Jedis to your maven or gradle project.
According to https://github.com/xetorthio/jedis :

Hopefully this helped, I am here to answer any more questions you have!
