Still an issue: Class Doctrine\Common\Proxy\AbstractProxyFactory does not exist

[lbayerl]

The issue mentioned here and to my understanding should have been fixed with version 1.10.1 with this merge still seems to exist for me.

After using composer create-project symfony/skeleton myproject and composer require doctrine/doctrine-bundle it installs 1.10.1 of the Doctrine bundle but I still receive the following error message:

In BaseNode.php line 422:
Invalid configuration for path "doctrine.orm.auto_generate_proxy_classes": Class Doctrine\Common\Proxy\AbstractProxyFactory does not exist

In Configuration.php line 714:
Class Doctrine\Common\Proxy\AbstractProxyFactory does not exist

Thank you. Did you take a look if the mentioned fix hasn't covered this bug completely or if this has another cause? Can you please contribute a failing test that reproduces this error?

Can you please post your configuration for Doctrine bundle (the doctrine: section)?

The Symfony recipe for this bundle naively assumes you will also use ORM and adds default section: https://github.com/symfony/recipes/blob/481ce0a9f1619c0bea95d1b37c4477a9880f7039/doctrine/doctrine-bundle/1.6/config/packages/doctrine.yaml#L19
So you need this to be deleted, with only dbal: left.

I just had the same issue described here. This is my doctrine configuration generated by recipe:

in config/packages/doctrine.yml

doctrine:
    dbal:
        # configure these for your database server
        driver: 'pdo_mysql'
        server_version: '5.7'
        charset: utf8mb4
        default_table_options:
            charset: utf8mb4
            collate: utf8mb4_unicode_ci

        url: '%env(resolve:DATABASE_URL)%'
    orm:
        auto_generate_proxy_classes: true
        naming_strategy: doctrine.orm.naming_strategy.underscore
        auto_mapping: true
        mappings:
            App:
                is_bundle: false
                type: annotation
                dir: '%kernel.project_dir%/src/Entity'
                prefix: 'App\Entity'
                alias: App

in config/packages/prod/doctrine.yml

doctrine:
    orm:
        auto_generate_proxy_classes: false
        metadata_cache_driver:
            type: service
            id: doctrine.system_cache_provider
        query_cache_driver:
            type: service
            id: doctrine.system_cache_provider
        result_cache_driver:
            type: service
            id: doctrine.result_cache_provider

To resolve, I had to manually run composer require doctrine/orm

If you're not planning to use the ORM, remove the orm configuration instead.

[alcaeus]

Closing here: this is an issue with the default configuration applied by the Symfony Flex recipe that doesn't take into account that ORM may not be installed. Nothing we can do here.

[Majkl578]

Maybe it could thow more meaningful error than "ReflectionException: Class ... not found"?

see #919 for an attempt to improve the reported error

Running composer require doctrine/orm did the trick. Thank you @barell .
