When I create a sample project, it creates the following code in app/controllers/app.go:

package controllers

import "github.com/robfig/revel"

type Application struct {
    *rev.Controller
}

func (c Application) Index() rev.Result {
    return c.Render()
}

But package revel doesn't exist. When "go get" runs, it downloads github.com/robfig/revel with the directory revel, yet you placed all the source code into package "rev". So what I had to do to get gocode to stop complaining was to create a symlink named rev to point to revel and change the import statements to import only rev, not revel.

The gist of this is: Please put the code into package revel if the final directory is named revel, or rename the final directory to rev.
