Alternatively you have a circular compilation dependency. This happens to people when they try to import route helpers inside a plug that they’re using in the router.
This reason that this is impossible is that the router must be compiled before the route helpers can exist. However, the router must have all its plugs compiled before it can exist. If you have a plug that imports the route helpers, you have a circle.
The solution is to make them remote calls, ie BpmServer.Router.Helpers.whatever_path
