Doctrine2 - No Metadata Classes to process

Question

Something is wrong with documentation or me. I do all what documentation says.

When i put in terminal :

$ php vendor/bin/doctrine orm:schema-tool:c         


        

Answer 1

I had the same problem when creating a new doctrine config in a new ZF2 module.

problem was caused by

'User\Entity' => 'property_entities'

the user part was from the old entity

'Property\Entity' => 'property_entities'

Changing that fixed the issue

Answer 2

I think you took the config example from Doctrine2: getting started:

$isDevMode = true;
$config = Setup::createAnnotationMetadataConfiguration([__DIR__."/src"], $isDevMode);

The trick is now that the Setup::createAnnotationMetadataConfiguration method uses a SimpleAnnotationReader by default. You can change this behaviour by changing the fifth parameter to false:

$isDevMode = true;
$config = Setup::createAnnotationMetadataConfiguration([__DIR__."/src"], $isDevMode, null, null, false);

This will force Doctrine to use the not-simple AnnotationReader which can handle your models now!

Answer 3

Try clearing the cache:

sudo -u www-data php app/console cache:clear --env=dev

Answer 4

Had the same issue with custom Doctrine installation. My solution was to re-set metadata driver:

$config->setMetadataDriverImpl(
    new Doctrine\ORM\Mapping\Driver\AnnotationDriver(
        new Doctrine\Common\Annotations\CachedReader(
            new Doctrine\Common\Annotations\AnnotationReader(),
            new Doctrine\Common\Cache\ArrayCache()
        ),
        ENTITY_DIR
    )
);

Solution from http://support.skipper18.com/1120/how-use-external-tools-generate-doctrine-getters-and-setters?show=1121#a1121 My scenario was generating entities from existing database

The newDefaultAnnotationDriver adds the namespace and the method comments state the following:

If $useSimpleAnnotationReader is true, the notation @Entity will work, otherwise, the notation @ORM\Entity will be supported.

Answer 5

In my case, the issue was with the number of asterisk used for the annotation

<?php

    namespace Models;

    use Doctrine\ORM\Annotation\{Id, Column, GeneratedValue, Entity};

    /** // I originally used one asterisk here and kept getting the error in question. Error disappeared after doubling the asterisk as it is in this answer
    * @Entity(repositoryClass="Doctrine\ORM\Annotation\Id")
    */
   class User {
   }

?>

Answer 6

Uncomment the one of the following lines in bootstrap.php:

// or if you prefer yaml or XML
//$config = Setup::createXMLMetadataConfiguration(array(__DIR__."/config/xml"), $isDevMode);
//$config = Setup::createYAMLMetadataConfiguration(array(__DIR__."/config/yaml"), $isDevMode);

Which depends if you created yaml or xml meta config files...

Hope this helps.
