Cannot make a static reference to the non-static method getConfig() from the type JavaPlugin - static

Question

I am trying to create a Minecraft plugin with a command that will set the world name into config.yml. Except I keep getting "Cannot make a static reference to the non-static method getConfig() from the type JavaPlugin" when I attempt to set the config. I have already searched around for several way to fix this but I have not understood have to implement other situations into mine.
Here is my code:
Main.java:
package me.Liam22840.MurderRun;
import org.bukkit.plugin.java.JavaPlugin;
import me.Liam22840.MurderRun.commands.HelpCommand;
import me.Liam22840.MurderRun.commands.SetmapCommand;
public class Main extends JavaPlugin {
#Override
public void onEnable(){
loadConfig();
new HelpCommand(this);
new SetmapCommand(this);
}
public void loadConfig(){
getConfig().options().copyDefaults(true);
saveConfig();
}
}
SetmapCommand.java:
package me.Liam22840.MurderRun.commands;
import org.bukkit.Location;
import org.bukkit.command.Command;
import org.bukkit.command.CommandExecutor;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import Utils.Utils;
import me.Liam22840.MurderRun.Main;
import me.Liam22840.MurderRun.getConfig;
public class SetmapCommand implements CommandExecutor{
private int count;
public SetmapCommand(Main plugin){
plugin.getCommand("Setmap").setExecutor(this);
}
#Override
public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
if (!(sender instanceof Player)){
sender.sendMessage("Only players can execute this command!");
return true;
}
Player p = (Player) sender;
Location b_loc = p.getLocation();
if(p.hasPermission("MurderRun.Setworld")){
Main.getConfig().set("Maps." + p.getName() + count + ".World", b_loc.getWorld().getName());
Main.saveConfig();
p.sendMessage(Utils.chat("&4Map Set"));
return true;
} else{
p.sendMessage("You do not have the required permissions to execute this command!");
}
return false;
}
}

You can't directly call the Main class, because it is not static. To call it, you should do this in your Setmap class and the constructor:
private Main plugin;
public SetmapCommand(Main plugin){
this.plugin = plugin;
plugin.getCommand("Setmap").setExecutor(this);
}
After you did this, you can use in your Setmap class:
plugin.saveConfig();
