Files listed in autoload['files'] error with Class not found in 2.2.0

[reece-oliver]

My composer.json:

  "autoload": {
    "classmap": [
      "scripts/composer/ScriptHandler.php"
    ],
    "files": [
      "load.environment.php"
    ]
  },

I am requiring:

"vlucas/phpdotenv": "^5.1",

When I run this command:

composer update

I get the following output:

PHP Fatal error:  Uncaught Error: Class 'Dotenv\Dotenv' not found in /Users/reeceoliver/Documents/ghe/apimesh/devportal-apim-profile/build/devportal/load.environment.php:16

And I expected this to happen:

If I downgrade from the new 2.2.0 release all works fine and command runs fine. Seems to do with something with files trying to be required before autoload now? Not 100% sure but definitely a regression from the previous release

[reece-oliver]

load.environment.php looks like

<?php

/**
 * This file is included very early. See autoload.files in composer.json and
 * https://getcomposer.org/doc/04-schema.md#files
 */

use Dotenv\Dotenv;

/**
 * Load any .env file. See /.env.example.
 *
 * Drupal has no official method for loading environment variables and uses
 * getenv() in some places.
 */
$dotenv = Dotenv::createUnsafeImmutable(__DIR__);
$dotenv->safeLoad();

@Seldaek I think the files of the root package should not be loaded when registering the autoloader for plugins, because the dependencies of the root package are not yet installed (for downloaded packages, we ensure that we install a package after its dependencies)

@reece-oliver workaround until the fix is done in composer: wrap the code in a class_exists check.

Preventing self-update with composer self-update 2.1.14 also works for now

Same issue in contao/contao/contao/core-bundle for instance:

Run composer install --no-interaction --no-progress
  composer install --no-interaction --no-progress
  shell: /bin/bash -e {0}
For additional security you should declare the allow-plugins config with a list of packages names that are allowed to run code. See https://getcomposer.org/allow-plugins
You have until July 2022 to add the setting. Composer will then switch the default behavior to disallow all plugins.

I think this is a regression caused by #10279
