Doctrine2 - No Metadata Classes to process - doctrine-orm

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:create
Output is :
No Metadata Classes to process
I read to many posts, and google and try to many examples but nothing.
http://docs.doctrine-project.org/projects/doctrine-orm/en/latest/tutorials/getting-started.html

Answer 1

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!

TL;DR: Make sure the type of metadata you created matches the "create metadata configuration" method you used.
I encountered the same problem while working through the Doctrine "Getting Started" guide. After looking through the Doctrine code a bit I figured out what was going wrong. Basically, the code in the tutorial in the "Obtaining the EntityManager" section is:
$config = Setup::createAnnotationMetadataConfiguration([__DIR__ . "/src"], $isDevMode);
A little further in the tutorial, in the "Starting with the Product" section, it shows us how to set up the metadata, with an example for each of the possible options for this. The tutorial says:
Metadata for entities are configured using a XML, YAML or Docblock Annotations. This Getting Started Guide will show the mappings for all Mapping Drivers. References in the text will be made to the XML mapping.
Because of this statement, I decided to use the XML configuration. Unfortunately, the createAnnotationMetadataConfiguration method in the tutorial code did not seem to be using the XML file I had created. (In hindsight, it seems much more obvious that this method is specifically referring to annotation metadata, not XML metadata!)
After I changed it to createXMLMetadataConfiguration instead, it worked as expected. So it looks like one possible source of this problem is that the "create metadata configuration" method you used may not match the type of metadata you created.

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

Answer 4

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.

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.

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

If you're using the XML mapping (using Setup::createXMLMetadataConfiguration()), you might want to pay attention to the following:
That your XML mapping files ends by .dcm.xml, not only by .xml.
That your XML file contains the full entity classname, inclusive of the namespace. For example, for a class Company\Solution\Models\User, you must have the Company.Solution.Models.User.dcm.xml mapping file in your XML path.

Answer 8

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 9

you must add the docstring for example:
<?php
// src/User.php
use Doctrine\ORM\Mapping as ORM;
/**
* #ORM\Entity
* #ORM\Table(name="users")
*/
class User
{
/**
* #ORM\Id
* #ORM\Column(type="integer")
* #ORM\GeneratedValue
*/
private $id;
/**
* #ORM\Column(type="string")
*/
private $name;
}

Try the following command:
php vendor/bin/doctrine-module orm:schema-tool:create
