Unknown column type "json" requested

I have installed AdminBundle, DoctrineORMAdminBundle, UserBundle and followed step by step the documentation of these bundles. But when i try to update the database, i got this error "Unknown column type "json" requested". It seems like the JsonType can't be find.
