Symfony version(s) affected

7.3.1

Description

When a class contains only imported custom types then they are ignored by Symfony\Component\TypeInfo\TypeContext\TypeContextFactory::resolveTypeAliases() because the parameter $toResolve is empty, however the parameter $resolved is not empty but completely ignored.

How to reproduce

This code fails:

/**
 * @phpstan-import-type ImportedType from ImportedTypeClass
 */
class ImportedTypeUser
{
    /** @var ImportedType */
    private array $importedTypeVariable;
}

But this code works:

/**
 * @phpstan-import-type ImportedType from ImportedTypeClass
 * @phpstan-type LocalType int
 */
class ImportedTypeUser
{
    /** @var ImportedType */
    private array $importedTypeVariable;
    /** @var LocalType */
    private int $localTypeVariable;
}

Possible Solution

Do not ignore non-empty $resolved in Symfony\Component\TypeInfo\TypeContext\TypeContextFactory::resolveTypeAliases().
