Grav: Can't get all pages from plugin's CLI

[tranduyhung]

I have a simple CLI script for my Grav plugin like this

<?php
namespace Grav\Plugin\Console;

use Grav\Console\ConsoleCommand;
use Symfony\Component\Console\Input\InputArgument;
use Symfony\Component\Console\Input\InputOption;
use Grav\Common\Grav;
use Grav\Common\Page\Page;
use Grav\Common\Page\Pages;

class ImportCommand extends ConsoleCommand {
  protected function configure() {
    $this->setName('import');
  }

  protected function serve() {
    $pages = Grav::instance()['pages']->all();
  }
}

However when I execute bin/plugin import import from terminal, I get this error:

$ bin/plugin import import
PHP Fatal error:  Uncaught Error: Call to a member function root() on null in /var/www/html/my-site/system/src/Grav/Common/Page/Pages.php:570
Stack trace:

With the above code I can get the pages from the plugin's main file but if put that code in CLI script, it doesn't work. I have Grav 1.3.10.

I have also tried to create a new Collection but I get a similar error, root page can't be found.

If I want to get all the pages from CLI script, what is the best way to do? Thanks in advance!

I believe the problem is that you are trying to access Pages before they are initialized. In the CLI you have to do this manually. See this plugin for an example: https://github.com/trilbymedia/grav-plugin-tntsearch/blob/develop/cli/IndexerCommand.php
