How to get list of all the actions of all controllers, including Plugins?

I'm trying to get all of the methods / actions of all the controllers from my CakePHP application.

I can not bring the methods of all controllers and I do not understand why.

I tried to import App::import and with App::uses , but get_class_methods() does not return methods / actions of all.

Here's what I created:

//Pega a lista de controllers da aplicação e adiciona num array;
$controllersApp = App::objects('controller');
//Varre o array de controllers da aplicação e adiciona cada item num array global
foreach($controllersApp as $c)
    {
        $temp_listControllers[] = $c;
    }
//Pega a lista de plugins
$plugins = App::objects('plugin');

//Varre o array de plugins
foreach($plugins as $plugin)
    {
        //Cria string para pegar lista de Controllers de cada Plugin: Plugin.controller
        $p = $plugin.'.controller';

        //Pega lista de controllers do Plugin corrente em $plugin
        $lista = App::objects($p);
        //Varre o array de controllers do Plugin corrente e adiciona cada item no array global
        foreach($lista as $l)
            {
                $temp_listControllers[] = $l;
            }
    }


foreach($temp_listControllers as $c)
    {
        //$r = str_replace("Controller", "", $c);
        $listControllers[] = $c;
    }    



foreach($listControllers as $controller)
    {

        $actions = get_class_methods($controller);
        echo "<hr /><h1>".$controller."</h1>";
        pr($actions);
    }

Am I doing something wrong? Is there any other way to do this?
