I was bitten by this trying to disable the autoincrement on my entities during an import from another system. This is the code to reproduce the problem:

use Doctrine\ORM\Mapping\ClassMetadata;

            $this->entityManager
                ->getClassMetadata('myClass')
                ->setIdGeneratorType(ClassMetadata::GENERATOR_TYPE_NONE);

The same code, working perfectly with with 2.x, was:

use Doctrine\ORM\Mapping\ClassMetadataInfo;

            $this->entityManager
                ->getClassMetadata('myClass')
                ->setIdGeneratorType(ClassMetadataInfo::GENERATOR_TYPE_NONE);
