“Class XXX is not a valid entity or mapped super class” after moving the class in the filesystem

Question

I had an entity class in Aib\\PlatformBundle\\Entity\\User.php

I had no problems trying to create its form class through

php app/ console doc

Answer 1

I resolved the same exception by deleting a conflicting autogenerated orm.php file in the bundle's Resources/config/doctrine folder; according to the documentation: "A bundle can accept only one metadata definition format. For example, it's not possible to mix YAML metadata definitions with annotated PHP entity class definitions."

Answer 2

In my case the problem was solved by changing my servers cache from eAccelerator to APC. Apparently eAccelerator strips all the comments from files which breaks your annotations.

Answer 3

I resolved this issue by setting $useSimpleAnnotationReader=false when creating the MetaDataConfiguration.

Answer 4

Very high possibility that you have PHP 5.3.16 (Symfony 2.x will not work with it). Anyway you should load check page on http://you.site.name/config.php If you had project not worked on hosting server, next lines must be removed in "config.php":

if (!in_array(@$_SERVER['REMOTE_ADDR'], array(
    '127.0.0.1',
    '::1',
))) {
    header('HTTP/1.0 403 Forbidden');
    exit('This script is only accessible from localhost.');
}

Goodluck!

I solved this by passing false as the second parameter to Doctrine\ORM\Configuration::newDefaultAnnotationDriver.

It took me a while of digging through Google and source code.

My case was sort of special since I was using a mapping pointing to another directory unrelated to the Symfony installation as I also had to use legacy code.

I had refactored legacy entities and they stopped working. They used to use @Annotation instead of @ORM\Annotation, so after refactoring it simply failed to read the metadata. By not using a simple annotation reader, everything seems to be okayish.

Had this problem - don't forget the annotation * @ORM\Entity like below:

/**
 * Powma\ServiceBundle\Entity\User
 *
 * @ORM\Entity
 * @ORM\Table(name="users")
 */
