Code:

if(cmd.getName().equalsIgnoreCase("bonuschest") && sender instanceof Player) {
            Player p = (Player) sender;
            Menu.show(p);
        }

@DaanSander

Code:

[LIST=1]
[*]org.bukkit.command.CommandException: Unhandled exception executing command 'bonu
[*]schest' in plugin HMCEssentials v1.0
[/LIST]

This means you tried to do something that could throw an exception without trying to handle it.

Code:

at me.daansander.hmcessentials.Menu.show(Menu.java:105) ~[?:?]

On line 105 in your 'Menu' class you have the problem

 

Moved to Bukkit Alternates

 

on line 105 is only this:
public HashMap<String, Integer> numbers = new HashMap<String, Integer>();

in eclipse the method worked fine but inteliJ not

 

@DaanSander

I dont know how to help you, it works fine on inteliJ for me
Did you import HashMaps?

 

yes but now i have multiple errors now when i try to register the events inside it says:
Error87, 62) java: constructor Menu in class me.daansander.hmcessentials.Menu cannot be applied to given types;
required: me.daansander.hmcessentials.HMCEssentials
found: no arguments
reason: actual and formal argument lists differ in length
