Symfony AutoMapperBundle requires symfony/serializer and symfony/property-access

[GromNaN]

On a fresh installation of Symfony 7.1, once AutoMapperBundle (version 9.0.1) is enabled in config/bundles.php, I get this error:

The service automapper.mapping.class_discriminator_from_class_metadata has a dependency on a non-existent service serializer.mapping.class_metadata_factory.

After installing the symfony/serializer package so that the service is registered by the FrameworkBundle, I get a new error:

[Symfony\Component\DependencyInjection\Exception\ServiceNotFoundException] You have requested a non-existent service serializer.normalizer.object.

This is solved by installing symfony/property-access. But then:

[Symfony\Component\DependencyInjection\Exception\ServiceNotFoundException] The service automapper.property_info.cache.inner has a dependency on a non-existent service property_info.phpstan_extractor.

This is solved by installing both phpstan/phpdoc-parser and phpdocumentor/type-resolver.

So I need to install this packages to work with the bundle:

composer require symfony/serializer symfony/property-access phpstan/phpdoc-parser phpdocumentor/type-resolver

This is the first time I install the package, so I'm not sure this is correct.

I think the installation of these dependencies could be better guided in the docs.

You are correct ! And we shouldn't force users to install Symfony's Serializer since it's now optional, I'll try to fix this.

Fixed thanks to #131 & #130
