Symfony2, Doctrine2 cache:warmup –env=prod Semantical Error?

Are you getting this strange error when trying to create cache for prod enviroment? and not getting this error on dev environemnt?

[Semantical Error] The annotation "@ORM\Table" in class Me\JeevanBundle\Entity\Repository\BlogRepository was never imported. Did you maybe forget to add a "use" statement for this annotation?

Easy to fix, Open the Entity file referring to this repository file and prefix it with “\” to give absolute namespaced path.
Issue:

@ORM\Entity( repositoryClass="Me\JeevanBundle\Entity\Repository\BlogRepository" )

Fix:

@ORM\Entity( repositoryClass="\Me\JeevanBundle\Entity\Repository\BlogRepository" )

Hope this helps!
