Doctrine 2 orm：尝试生成实体时的转换映射错误

Question

I use --filter to generate an specific entity like "Tag" from tag table but, Doctrine returning the following error:

doctrine orm:convert-mapping --from-database annotation Entities/ --filter "Tag"

[Doctrine\ORM\Mapping\MappingException] 
Property "pseReference" in "ProjectStepConfigElement" was already declared, but it must be declared only once

So I remove the entire Entities folder from my project to regenerate all Entities from database via reverse engineering.

But when run the following command to generate all entities to Entities/ folder with annotations:

doctrine orm:convert-mapping --from-database annotation Entities/

Doctrine return the same error:

[Doctrine\ORM\Mapping\MappingException] 
Property "pseReference" in "ProjectStepConfigElement" was already declared, but it must be declared only once

EDIT:

If I filter by entity with Entities/ directory empty the new entities is generated. So I generate all new entities that not exists before, add with git add [filePath], and return the old entities with git checkout -- . and clean files~ with git clean -f. Commit and all is working fine.

Why Doctrine returning the error:

[Doctrine\ORM\Mapping\MappingException] 
Property "pseReference" in "ProjectStepConfigElement" was already declared, but it must be declared only once

What's happen? when
