AsyncTask not working

I am trying to use an AsyncTask to make an HTTP call; however, it does absolutely nothing. Code:

PHP:

<?php

namespace HittmanA\PMPluginManager;

use pocketmine\event;
use pocketmine\Server;
use pocketmine\command\CommandSender;
use pocketmine\command\Command;
use pocketmine\plugin\PluginBase;
use pocketmine\Player;
use pocketmine\event\Listener;
use pocketmine\utils\Utils;
use pocketmine\utils\Config;
use pocketmine\command\ConsoleCommandSender;
use pocketmine\scheduler\AsyncTask;

class Plugin extends AsyncTask
{
    public function __construct($name, $sender)
    {
        $this->name = $name;
        $this->sender = $sender;
    }
    public function onRun()
    {
        print("test");
        $url = "https://poggit.pmmp.io/releases.json?name=".$this->name;
        $register = Utils::getURL($url);
        $JSONParsedRegister = json_decode($register);
        if (count($JSONParsedRegister) != 0)
        {
            //$sender->sendMessage("'".$name."' was found on Poggit. Downloading now...");
            $latestVersion = $JSONParsedRegister[0];
            $pluginVersion = $latestVersion->version;
            $this->version = $pluginVersion;
            //$sender->sendMessage("Found the requested version. Downloading version ".$this->version."...");
            $poggitURL = $latestVersion->artifact_url;
            $this->url = $poggitURL;
            $pluginName = $latestVersion->project_name;
            $this->name = $pluginName;
            $this->download_url = $poggitURL."/".$pluginName.".phar";
            $this->ready_to_download = true;
        } else {
            //$sender->sendMessage("Sorry but '".$name."' isn't listed on Poggit!");
            $this->ready_to_download = false;
        }
        $code = Utils::getURL($this->download_url);
        $this->setResult($code);
        //$this->sender->sendMessage($pluginToDownload." has been installed successfully!");
        //$this->sender->sendMessage("Reloading server...");
    }
    public function onCompletion(Server $server)
    {
        
        $pluginCode = $this->getResult();
        $fp = fopen ($this->getServer()->getDataPath()."/plugins/".$this->name.".phar", 'w+');
        fwrite($fp, $pluginCode);
        fclose($fp);
        $this->getServer()->dispatchCommand(new ConsoleCommandSender(), 'reload');
    }
}

Nothing every happens when I make a new instance of this class. No file is created and it doesn't even print out "test". Here is the code I use to instantiate the class:

PHP:

$plugin = new Plugin($pluginToDownload, $sender);

Why does the AsyncTask do nothing?

 

You aren't scheduling the task, are you?

 

Oh ok. I assume that goes in the MainClass and not the actual class I want to run as a task, right?

 

You can call it in your AsyncTask class's constructor if that helps.

 

That would be best. Thanks @dktapps and @Muqsit!

 

Yeah, I don't recommend calling it in the constructor either.

 

Thanks for the advice @SOFe ! I figured that something like this would probably be the case so I did indeed schedule the task at the end of the constructor.
