Here is some code to help understand the problem. I am trying to have independant package registering scheduled tasks and so far all I could do was running the tasks in the kernel and one of my package tasks. When I have more than one package registering tasks, only one package and the app kernel run it's task. When I deactivate the package that the task run (for example the package "something"), the other package "console" run his task along with the app Kernel tasks. So my question is what do I do wrong to have multiple package able to run their own tasks. Thanks!

I get this in the schedule.log file:

PACKAGE NAME IS project
PACKAGE NAME IS something
PACKAGE NAME IS project
PACKAGE NAME IS something

Here is the source of the important you need to see to understand my problem.

file app/Console/Kernel.php

<?php 

namespace App\Console;

use Illuminate\Console\Scheduling\Schedule;
use Illuminate\Foundation\Console\Kernel as ConsoleKernel;

/**
 * @see https://laravel.com/docs/5.2/scheduling
 */
class Kernel extends ConsoleKernel
{
    /**
     * The Artisan commands provided by your application.
     *
     * @var array
     */
    protected $commands = [
        Commands\TestCommand::class
    ];

    /**
     * Define the application's command schedule.
     *

    {
        $schedule->command('test:command project')->everyMinute()->appendOutputTo(base_path('schedule.log'));
    }
}

file app/Console/Commands/TestCommand.php

This is only to debug that the task has been run. I am running a tail -f schedule.log in my terminal and see the execution every minute.
