Doctrine migration ignores #Table Annotation in #Entity definition - symfony

Question

I have the following Doctrine Entity in Symfony 4.2:
When I run the migration the unique constraints and the indexes are not generated. The result of the Entity are just the following indexes in MySql:
PRIMARY (id)
identifier (identifier), Unique
Media.php
<?php
// src/Entity/Media.php
namespace App\Entity;
use Doctrine\ORM\Mapping as ORM;
use Doctrine\ORM\Mapping\UniqueConstraint;
/**
* Common\Model\Entity\Media
*
* #Entity
* #Table(name="media",
* uniqueConstraints={
* #UniqueConstraint(name="virtual_unique",
* columns={"virtualname", "virtualfolder"})
* }
* indexes={
* #Index(name="idx_virtual", columns={"virtualname", "virtualfolder"})
* #Index(name="idx_identifier", columns={"identifier"})
* }
* )
*/
/**
* #ORM\Entity(repositoryClass="App\Repository\MediaRepository")
*/
class Media
{
/**
* #ORM\Id
* #ORM\GeneratedValue
* #ORM\Column(type="integer")
*/
private $id;
/**
* #ORM\Column(type="string", nullable=true, options={"unique": true})
*/
private $identifier;
/**
* #ORM\Column(type="string", length=255, nullable=false)
*/
private $virtualname;
/**
* #ORM\Column(type="string", length=255, nullable=true)
*/
private $virtualfolder;
}

Answer 1

First, you have multiple annotation blocks for the same class. Just merge them and have a single annotation block for that entity.
And you are using serveral annotations directly, but not importing their definitions. Specifically:
#Entity
#Index
#UniqueConstraint
#Table
Either you:
Use them prefixed by #ORM(since you are doing use Doctrine\ORM\Mapping as ORM)
This is the most convenient and the one that's usually applied.
A complete fix:
/**
* Common\Model\Entity\Media
*
* #ORM\Entity(repositoryClass="App\Repository\MediaRepository")
* #ORM\Table(name="media",
* uniqueConstraints={
* #ORM\UniqueConstraint(name="virtual_unique",
* columns={"virtualname", "virtualfolder"})
* },
* indexes={
* #ORM\Index(name="idx_virtual", columns={"virtualname", "virtualfolder"}),
* #ORM\Index(name="idx_identifier", columns={"identifier"})
* }
* )
*/
class Media
{}
Or, you use the full namespace declaration in those annotations
You could also use the annotations with the full namespace, like #Doctrine\ORM\Mapping\Table, #Doctrine\ORM\Mapping\UniqueConstraint, etc; but that gets unnecessarily verbose very quickly.
Or, you could import each of the annotations independently
use Doctrine\ORM\Mapping\Table;
use Doctrine\ORM\Mapping\Index;
use Doctrine\ORM\Mapping\Entity;
use Doctrine\ORM\Mapping\UniqueConstraint;
But it also seems wasteful.
The approach you'll see on the docs is the first one. Import Doctrine\ORM\Mapping as ORM, and use the annotations hanging from there.

Probably you need change #Table to #ORM\Table and remove #Entity
try this:
/**
* #ORM\Entity(repositoryClass="App\Repository\MediaRepository")
* #ORM\Table(name="media",
* uniqueConstraints={
* #UniqueConstraint(name="virtual_unique",
* columns={"virtualname", "virtualfolder"})
* }
* indexes={
* #ORM\Index(name="idx_virtual", columns={"virtualname", "virtualfolder"})
* #ORM\Index(name="idx_identifier", columns={"identifier"})
* }
* )
*/

Clearing my cache did the trick for me.
I tried a few other suggestions, but after a cache:clear I got the index in my migration.
