How to work with plugins in Cakephp 3.6 or 3.6.1

Question

How to work with plugins in Cakephp 3.6 or 3.6.1.

Until version 3.5.13 I worked without problem, installed via Poser and loaded with bin/cake plugin load Name

But in version 3.6 that was quite changed, I install without problem with Composer require user/plugin name

But when I’m gonna charge bin/cake plugin load Nameplate

He throws me this message:

Your Application class does not have a bootstrap() method. Please add one.

I received a tip to add the code below in src/Application.php

public function bootstrap()
{   
    parent::bootstrap();
}

I can load it. At least it doesn’t give an error message. It says it has. But when I try to run Bake to generate code it tells me:

bin/cake Bake

all groups -t CakeAclBr
PHP Fatal error:  Uncaught InvalidArgumentException: The plugin class `CakeAclBr\Plugin` cannot be found. Ensure your autoloader is correct. in /backup/www/cake361/vendor/cakephp/cakephp/src/Http/BaseApplication.php:127

I couldn’t go through with it from here. There is some hint. Thank you!
