PHP 7.4: Undefined method named "getAttributes" of class "ReflectionClass"

[jjarolim]

Bug Report

Q	A
BC Break	no
Bundle version	1.21.1
Symfony version	5.4
PHP version	7.4.29

Summary

After installing VichUploaderBundle via composer, symfony throws the following error:

Attempted to call an undefined method named "getAttributes" of class "ReflectionClass" in AttributeReader.php line 20.

It seems that ReflectionClass::getAttributes was introduced in PHP 8 and is not available in PHP 7.4: https://www.php.net/manual/en/reflectionclass.getattributes.php

composer.json php requirement and platform config would be set to 7.4:

{
  "require": {
    "php": "7.4"
  },
  "config": {
    "platform": {
      "php": "7.4"
    }
  }
}

Current behavior

Project throws compile time exception

How to reproduce

Just install bundle on a fresh symfony 5.4 project on PHP 7.4.x

Expected behavior

No usage of that method on PHP < 8

That's because you cannot use attributes in PHP 7.4 Use annotations instead (or XML mapping or yaml)

Ah OK thanks!

For the first try I just copied the package configuration from the documentation page Basic usage without questioning what

metadata:
  type: attribute

means.

Maybe some clarification in the sample would be cool:

metadata:
  type: attribute # PHP 8: Use attributes @see https://www.php.net/manual/en/language.attributes.overview.php

But nevertheless many thanks for the help!

Best regards from Salzburg,
