Hey guys!  I just wonder is there is any posibility to make my ide know about namespaces that i working with. I am not sure is it even possible but maybe one of you know what to do to get things work properly. Right know i have some plugin that i use with doctrine, and there is also package that my IDE don’t know about it.  Btw. I have phpStorm Symfony and Shopware plugin on.  My PHPStorm is 2019.1 version. , I am using Shopware 5. Here is a code: ![](https://europe1.discourse-cdn.com/flex013/uploads/shopware/original/2X/4/4d997577926aef1ad9c3aef7d19a9ab9d767cf0c.png) And anywhere where i use SchemaTool object reference. ![](https://europe1.discourse-cdn.com/flex013/uploads/shopware/original/2X/e/ea23f3413ea5b0a14073fb590bf89e660be316aa.png) Thanks for any suggestions. ---

Hey @komoito‍, this is the Shopware **6** area, is that right? Are you trying this in Shopware 6? Because there is no such class in Shopware 6, that’s why he fails to find that namespace. It’s actually not existing. Same for the class _Shopware\Components\Plugin_. That seems to be Shopware 5 code. Kind regards, Patrick  ![Shopware](https://europe1.discourse-cdn.com/flex013/uploads/shopware/original/1X/86c57fbace799dd4eb1f1b8a2d3bdc1733f0aea1.png "Shopware") ---

  [@Patrick Stahl]([http://forum.shopware.com/profile/1869/Patrick](http://forum.shopware.com/profile/1869/Patrick) Stahl “Patrick Stahl”)‍ do you suggest if I used shopware 6 all dependencies and others stuff should work properly?    ---

Hey @komoito‍, no, I was just wondering, because initially your thread was in the Shopware 6 section, yet you were talking about Shopware 5. Does the referenced class _Doctrine\ORM\Tools\SchemaTool_ exist in your project? Usually, there shouldn’t be any issues with that namespace in Shopware 5. Must be an IDE related issue then.
