Symfony2表单文件夹(Symfony2 Form folder)

 我需要创建一个表单类，我正在关注http://symfony.com/doc/current/book/forms.html中的symfony书。 
 
 我正在尝试在src / Acme / TaskBundle / Form / Type / TaskType.php中创建一个表单，但是当我查看项目中的文件夹结构时，没有“Form”文件夹。 
 
 我尝试手动创建Form文件夹，在src / Acme / TaskBundle /中，我在表单文件夹和TaskType.php文件中遇到错误（名称空间Acme \ TaskBundle \ Form \ Type Expected：Identifier）。 
 
 有没有办法以自动方式创建窗体文件夹？ 或者我如何手动创建？ 

I need to create a form class,I'm following the symfony book in http://symfony.com/doc/current/book/forms.html
 
I am trying to create a form in src/Acme/TaskBundle/Form/Type/TaskType.php, but when I look at the folder structure on my project there is no "Form" folder. 
 
I try to create the Form folder manually, in src/Acme/TaskBundle/, I get an error in the the Form Folder and in the TaskType.php files ( namespace Acme\TaskBundle\Form\Type Expected:Identifier).
 
Is there a way to create the Form folder in an automatic way? Or how can I create in manually?
