NullPointerException

[stof]

I enabled the plugin in my PhpStorm project working on https://github.com/Behat/Symfony2Extension, which gives me autocompletion on places using the DI component (building of service definitions). However, I got a NullPointerException. I think it might be related to the fact that there is no dumped compiled container in the project. Here is the stack trace:
