Doctrine ReflectionException property does not exist

Question

I'm trying to add Doctrine on top of an existing database. I let Doctrine generate annotated entities and adjusted from there. When I try to load the entity below I get the error PHP Fatal error: Uncaught exception 'ReflectionException' with message 'Property Users\\User::$resellerID does not exist'

class User
{
    /* ... */

    /**
     * @var \Doctrine\Common\Collections\Collection
     *
     * @ORM\ManyToOne(targetEntity="\Resellers\Reseller")
     * @ORM\JoinTable(name="reseller",
     *   joinColumns={
     *     @ORM\JoinColumn(name="resellerID", referencedColumnName="resellerID")
     *   },
     *   inverseJoinColumns={
     *     @ORM\JoinColumn(name="resellerID", referencedColumnName="resellerID")
     *   }
     * )
     */
    private $reseller;

    /* ... */
}

Both the user and reseller tables have resellerID columns. My understanding is that for joining ID columns you don't add the ID columns as properties in the entity class. So what's causing the ReflectionException?

Answer 1

Since I had renamed the autogenerated property from resellerID to reseller (after trying to use it) it turns out I needed to clear the Doctrine cache.

php vendor/bin/doctrine.php orm:clear-cache:result
php vendor/bin/doctrine.php orm:clear-cache:query
php vendor/bin/doctrine.php orm:clear-cache:metadata

Or, if you are using Symfony with Doctrine:

php bin/console doctrine:cache:clear-result
php bin/console doctrine:cache:clear-query
php bin/console doctrine:cache:clear-metadata

Answer 2

For me clearing the PHP APC cache was the solution

<?php
apc_clear_cache();
