can u help me

 

did you define your main class in your plugin.yml && did you make sure you make a package?

Package should look like this:
GoldStuff > src > me > barmyaaron > goldstuff > [classes]

 

it seems your main plugin class is in an unnamed 'default' package. Put the main plugin class in a named package. Maybe this will help

 

i will have alook know

My Plugin.yml name: Goldstuff
main: me.barmyaaron.Goldstuff
author: barmyaaron
version: 1.0
commands:

Goldstuff:
description: Turn everything into Gold.

Same error

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

you have to define a class after the package....

main: me.barmyaaron.Goldstuff.<main class>

 

i have just done That and i get the same Error

 

Your YAML syntax seems wrong with commands:

Code:

commands:
 
Goldstuff:
description: Turn everything into Gold.

should be

Code:

commands:
    Goldstuff:
        description: Turn everything into Gold.

Also, I'm guessing your problem is with the "main:" in your plugin.yml
I'll assume your package name is "me.barmyaaron.Goldstuff". If that's true, you want main to be like this:

Code:

main: me.barmyaaron.Goldstuff.<Main class name>
