Hello, so I've recently got into java and I'm pretty good with it so I decided to create a plugin for my server that links in with WG and factions, it all works fine but when I try to define the package right at the top of the page I get this error:

The type com.google.gson.Gson cannot be resolved. It is indirectly referenced from required .class files

I have tried to remove the JRE library and re-adding it, but no luck. the code for the class file is as follows:

package me.HexCraft;

import org.bukkit.ChatColor;
import org.bukkit.Location;
import org.bukkit.Material;
import org.bukkit.Server;
import org.bukkit.block.Block;
import org.bukkit.entity.Entity;
import org.bukkit.entity.Player;
import org.bukkit.event.Event.Result;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.block.Action;
import org.bukkit.event.block.BlockPlaceEvent;
import org.bukkit.event.player.PlayerInteractEntityEvent;
import org.bukkit.event.player.PlayerInteractEvent;
import org.bukkit.event.player.PlayerShearEntityEvent;
import org.bukkit.inventory.ItemStack;
import org.bukkit.plugin.PluginManager;

import com.massivecraft.factions.Factions;

public class HexListener
implements Listener

public HexListener(HexRestrict plugin)
{
this.plugin = plugin;
plugin.getServer().getPluginManager().registerEvents(this, plugin);
}

public void onPlayerShear(PlayerShearEntityEvent event)

if (event.getEntity().toString() == "CraftSheep") {
event.setCancelled(StopShear(event.getPlayer(), event.getEntity(), event.getEntity().getLocation()));
}
}

event.setCancelled(StopShear(event.getPlayer(), event.getRightClicked(), event.getRightClicked().getLocation()));

event.setCancelled(StopShear(event.getPlayer(), event.getRightClicked(), event.getRightClicked().getLocation()));
}

The message, "The type com.google.gson.Gson cannot be resolved. It is indirectly referenced from required .class files," means you need to add a library that contains the type, com.google.gson.Gson, to the project's Java Build Path. The message is literally telling you that some other class on the build path already refers to it.

So? Doesn't JDT exactly tell you where the error is? I bet it does. Now
you need to understand what's going on. Here's a nice read for you:

I think these might be good:

Haven't seen this series, but another one by the same person, and really
liked the style.
