make:migration does not detect database changes on make:entity ManyToMany relation

[quentint]

Hey all,
I generated a Purchase entity and a Game one with make:entity. I then added a games ManyToMany relation on Purchase (also using make:entity).

I then ran make:migration but got a surprising

[WARNING] No database changes were detected.

I tried adding a @ORM\JoinTable annotation on private $games; but the result remained the same.

Not sure what to do next, and how to generate a migration class. Anyone also experienced this?

I'm having a similar problem after updating symfony to 4.3.8, have you tried removing cache?

[quentint]

I have, yes. I didn't mention it, but I'm using Symfony 5.0.

@quentint It looks like this is a doctrine bug symfony/recipes#688

Yes this is currently an issue with wrongly configured caches on DoctrineBundle. We are working on a fix.

See doctrine/DoctrineBundle#1073

Oh great, thanks for letting me know!

I can confirm that calling doctrine:cache:clear-metadata before make:migration fixes the issue. But oddly enough, it displays that message:

[ERROR] No cache entries were deleted.

Working anyway 👍
