Fatal Error on Symfony 2 CRUD command

Question

Good Mourning!

I have an error while performing the CRUD command, I see this error in the console.

Fatal error: Class 'Doctrine\Bundle\DoctrineBundle\Mapping\MetadataFactory'
not found in [route-to-project]\vendor\sensio\generator-bundle\Sensio\Bundle
\GeneratorBundle\Command\GenerateDoctrineCommand.php on line 36

searching the web I found that the upgrade Doctrine is not compatible with the bundle of sensiogenerator and should rollback to a previous version.

But I can not do it because I have several installed bundles that are not compatible with an early version of doctrine.

I hava a solution or I have to create the controllers manually?

Thank you!

this is my composer.json

Answer 1

I found the solution! Just create a MetadataFactory.php file in vendor\doctrine\doctrine-bundle\Doctrine\DoctrineBundle\Mapping whit the MetadataFactory class

here the file

Answer 2

Better Solution

Anyone using Symfony 2.7 or lower might run into this.

Here is the commit where the problem was fixed

You could patch this directly to your codebase, but modifying core vendor files makes composer redundant.

A better solution is to upgrade the SensioGeneratorBundle to v2.5, which appears to be compatible with Symfony v2.7

In composer.json change this: "sensio/generator-bundle": "2.5.*"

Then run composer update (be warned - this will update everything in your composer file, which may not be desirable.)

Alternative Solution

Only update a single package

composer require sensio/generator-bundle:2.5.3
