Doctrine MappingException with message 'The target-entity Entity\\ItemsBags cannot be found in 'Entity\\Players#itemsBag'

Question

Good day. I'm already on my second day and I can not understand what's the matter ... I get the error in runtime:

PHP Fatal error: Uncaught exception 'Doctrine\ORM\Mapping\MappingException' with message 'The target-entity Entity\ItemsBags cannot be found in 'Entity\Players#itemsBag'.' in /var/www/vendor/doctrine/orm/lib/Doctrine/ORM/Mapping/MappingException.php:762 Stack trace: #0./var/www/vendor/doctrine/orm/lib/Doctrine/ORM/Mapping/ClassMetadataInfo.php(1028): Doctrine\ORM\Mapping\MappingException::invalidTargetEntityClass('Entity\\ItemsBag...', 'Entity\\Players', 'itemsBag') #1./var/www/vendor/doctrine/orm/lib/Doctrine/ORM/Mapping/ClassMetadataFactory.php(272): Doctrine\ORM\Mapping\ClassMetadataInfo->validateAssociations() #2./var/www/vendor/doctrine/orm/lib/Doctrine/ORM/Mapping/ClassMetadataFactory.php(251): Doctrine\ORM\Mapping\ClassMetadataFactory->validateRuntimeMetadata(Object(Doctrine\ORM\Mapping\ClassMetadata), NULL) #3./var/www/vendor/doctrine/common/lib/Doctrine/Common/Persistence/Mapping/AbstractClassMetadataFactory.php(332): Doctrine\ORM\Mapping\ClassMetadataFactory->doLoadM in /var/www/vendor/doctrine/orm/lib/Doctrine/ORM/Mapping/MappingException.php on line 762

When I check the doctrine, and the update, everything goes well:

root@comp:# php vendor/bin/doctrine orm:schema:update --force Updating database schema... Database schema updated successfully! "4" queries were executed

root@comp:# php vendor/bin/doctrine orm:validate-schema [Mapping] OK - The mapping files are correct. [Database] OK - The database schema is in sync with the mapping files.

I tried to clear the cache, delete the proxy and regenerate them, but nothing produced results ...

root@comp:# php vendor/bin/doctrine orm:clear-cache:metadata
Clearing ALL Metadata cache entries
Successfully deleted cache entries.
root@comp:# php vendor/bin/doctrine orm:clear-cache:query

    private $itemsBag;

ItemsBags.php

namespace Entity;
use Doctrine\Common\Collections\ArrayCollection;

/**

class ItemsBags{

    ...

    /**

     *
     * @OneToOne(targetEntity="Players", inversedBy="itemsBag")
     * @JoinColumn(name="player_id", referencedColumnName="id")
     */
    private $player;

    ...

}

Tell me please, what am I doing wrong?

You could try using the fully qualified names: @OneToOne(targetEntity="\Entity\ItemsBags", mappedBy="player") and @OneToOne(targetEntity="\Entity\Players", inversedBy="itemsBag"). Though it does seem to be looking for them there... — OrderAndChaos
Have you configured the psr-4 root? Look for psr-4 in your composer file — OrderAndChaos
I try to using the fully qualified names, but this too no effect. @Sarcoma I did not quite understand your question... I use only doctrine in my project, using composer. I initialize doctrine like this: pastebin.com/AYB7Zvnd — Mr. DotNet

Thanks to @Sarcoma. I just forgot to specify autoload section in my composer.json

  "autoload": {
    "psr-4": { "": "core/" }
  },

P.S Can enyone me tell, why my project running normal before?) Before I too have many entinties, no have that section in my composer.json, but all works fine.
