Fixing Symfony Console 7.3 Deprecation Warning

Issue Description

When running composer run dev in Laravel 12.16.0 applications with PHP 8.3.14, users were encountering repeated truncated deprecation warnings from Symfony Console 7.3:

[logs] WARNING Since symfony/console 7.3: Method "Symfony\Component\Console\Command\Command::getDefaultDescription()" is deprecated and will be removed in Symfony 8.0, use the #[AsCommand] attribute instead.

The full log message:

{
  "message": "Since symfony/console 7.3: Method \"Symfony\\Component\\Console\\Command\\Command::getDefaultDescription()\" is deprecated and will be removed in Symfony 8.0, use the #[AsCommand] attribute instead. in /Users/Kyrian/Packages/filament-daterange-picker/playground/vendor/symfony/deprecation-contracts/function.php on line 25",

Root Cause

The issue was related to Laravel's ClosureCommand class not having a $description property defined. In Symfony Console 7.3, the getDefaultDescription() method was deprecated in favor of using the #[AsCommand] attribute, and Symfony was generating deprecation warnings because of this.

Fix Summary

The fix involved adding a $description property to the ClosureCommand class in Laravel's codebase:

/**
 * The console command description.
 *
 * @var string
 */
protected $description = '';

This ensures that when closure commands are created, they have a proper description property that is compatible with Symfony Console 7.3's expectations.

Implementation Details

1. Added a $description property to the ClosureCommand class in:

   • /src/Illuminate/Foundation/Console/ClosureCommand.php

2. Created a test to verify that closure commands work correctly:

   • /tests/Integration/Foundation/Console/ClosureCommandTest.php

This approach follows the same implementation pattern used in Laravel 11, as demonstrated in PR #55888.

Benefits

• Eliminates deprecation warnings when running Artisan commands
• Ensures compatibility with future versions of Symfony Console
• Follows the recommended Symfony practice of defining descriptions via properties
