Trouble with importing annotations

Question

I\'m working on a CodeIgniter project in which I\'m using Doctrine2 and the Symfony2 Validator component.

All my Doctrine2 entities use Doctrine\\ORM\\Mapping

Answer 1

I had a similar issue when using Silex, Doctrine2 and the Symfony-Validator.

The solution was to avoid using the SimpleAnnotationsReader and instead using the normal AnnotationReader (have a look at Doctrine\ORM\Configuration::newDefaultAnnotationDriver). You can then preface every entity with ORM\ (and of course inserting use Doctrine\ORM\Mapping as ORM; in every entity).

Answer 2

I resolved this issue by adding the following to my entity file:

use Doctrine\ORM\Mapping as ORM;

So my file now looks like:

<?php

namespace Acme\CustomBundle\Entity;

use Doctrine\ORM\Mapping as ORM;

/**
 * Example
 *
 * @ORM\Entity
 * @ORM\Table(name="example")
 *
 */
class Example
{
    /**
     * @ORM\Column(type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     *
     * @var integer
     */
    private $id;

    /**
     * @ORM\Column(type="string", length=125)
     *
     * @var string
     */
    private $title;

    /**
     * Get id
     *
     * @return integer
     */
    public function getId()
    {
        return $this->id;
    }

    /**
     * Set title
     *
     * @param string $title
     *
     * @return Example
     */
    public function setTitle($title)
    {
        $this->title = $title;

        return $this;
    }

    /**
     * Get title
     *
     * @return string
     */
    public function gettitle()
    {
        return $this->title;
    }

}

Answer 3

I was getting the same error message "[Semantical Error] The annotation "@Entity" in class Entity\User was never imported. Did you maybe forget to add a "use" statement for this annotation?".

The problem was that I had alias for ORM and did not used it for the annotation.

I had this: @OneToOne(targetEntity="CompanyProduct")

And correct was this: @ORM\OneToOne(targetEntity="CompanyProduct")

If you are testing and your tests fail because of this. Make sure you have the right autoload configured in your phpunit settings.

For a very specific scenario, my problem was upgrading my symfony version whereas before i had the bootstrap.cache.php file, but on a new version, it is app/autoload. I had to change my phpunit.xml config file and set my bootstrap option to that file bootstrap="autoload.php"

Answer 5

My problem solved by adding:

use Doctrine\ORM\Mapping\HasLifecycleCallbacks;

Answer 6

Add use statements for every annotation you have used in your entities. for example:

use Doctrine\ORM\Mapping\Entity;
use Doctrine\ORM\Mapping\Table;
use Doctrine\ORM\Mapping\Id;
use Doctrine\ORM\Mapping\Column;
use Doctrine\ORM\Mapping\GeneratedValue;

But you may not interesting to use this method. You can write all use statements to one file and just include it in your entities.
