I am working on symfony project and I am using annotations for controllers and so on.
But I got warning on every use or import I have in annotations. I am desperate a I have tried to rebuild cache and restart multiple times.
I have Symfony2 plugin and Symfony2 - Clickable Views installed but uninstalling and installing them does not help.
Make sure that you have PHP Annotations plugin installed and enabled.
It's a 3rd party plugin (hence not bundled by default) that handles annotations and all around it.
