Solved Help with InvMenu

So I'm running InvMenu from source using Devirion and I get this error:
[Server thread/CRITICAL]: Error: "Class 'test\test\InvMenuHandler' not found"

My code:

PHP:

 public function onEnable() {

        if(!InvMenuHandler::isRegistered()){
    InvMenuHandler::register($this);
        }

I've also done

PHP:

use muqsit\invmenu\InvMenu;

I have InvMenu running from Source in the /virions folder, Devirion as a .phar in /plugins and the plugin itself is running from source in /plugins

 

You forgot

PHP:

use muqsit\invmenu\InvMenuHandler;
