Plugin error saying NullPointerExeception.null

[PandaPlaysAll]

Main Class;


Command Class;


For some reason the console errors aren't pointing me in any direction.

Side not. what is the difference between 'awt' and 'util'
as previously I made a error for importing

Don't create your own

public MenuCommand(Main main) {
this.main = main;
}

Just do:
new MenuCommand()
When you register the command.

A NullPointerException is a Runtime Exception that is being thrown when a pointer reference is null. In this situation, you are trying to call the .setExecutor() method of the class implementing the CommandExecutor interface.

The spigot framework will grab the commands from the plugin.yml configuration and if it does not find anything there, it will not create the object, therefor, you cannot set an executor on something that does not exist.

Please look into more details of what Runtime Exceptions are, what a try-catch block is, how to throw exceptions and OOP concepts in general. It will help you greatly when working with such an extensive API.

Look into Encapsulation, Override, Overload, Interfaces, Class Inheritance, Abstract Classes, repetitive patterns, decisional patterns and declarations for best understanding of the topic.

As for your imports, they are two different packages from two different sources. You need to look into all of the libraries that are inside the spigotAPI in order to properly understand the tools you can work with.

You also imported the wrong ChatColor! The correct import would be org.bukkit.chatcolor.

Technically it doesn't matter if you use the spigot import or the bukkit version, they're just converted to a string using the prefix "§"<number of code> when compiled anyways.

Thinking of situations where the server does not have the md_5 package, it will throw a NoClassDefFoundError. But I see your point, considering most of the plugins nowadays are built on the spigot API which contains that package.
