Golang 1.5 vendors - Cannot find package

Trying to build my project in go lang using version 1.5 with GO15VENDOREXPERIMENT="1" turned on to ensure I look for the vendors locally.

My structure is:

apps_api
   main.go
   build.sh
   src
      controllers
      models
      views
   vendor
      github.com
      golang.org
      .....

build.sh contains

export GO15VENDOREXPERIMENT="1"
export GOPATH=`pwd`
go build .

controller file example

import (
    "models"
    "views"

    "github.com/gin-gonic/gin"
)

But i get lots of errors saying package not found see below for exmaple

src/controllers/app-versions.go:10:2: cannot find package "github.com/asaskevich/govalidator" in any of:
	/Users/ereeve/.gvm/gos/go1.5/src/github.com/asaskevich/govalidator (from $GOROOT)
	/Users/ereeve/Documents/gocode/src/apps_api/src/github.com/asaskevich/govalidator (from $GOPATH)

src/controllers/index.go:4:2: cannot find package "github.com/chnlr/baseurl" in any of:
    /Users/ereeve/.gvm/gos/go1.5/src/github.com/chnlr/baseurl (from $GOROOT)
    /Users/ereeve/Documents/gocode/src/apps_api/src/github.com/chnlr/baseurl (from $GOPATH)

If i add these lines into my build.sh file it will build, but I don't want to use go get because I am using go 1.5 with the vendors locally inside my project to avoid dependancies.

# go get github.com/gin-gonic/gin
# go get github.com/go-sql-driver/mysql
# go get github.com/rif/cache2go
....

Any ideas what I am doing wrong?

IIRC, GO15VENDOREXPERIMENT will work only if the package you're building is inside $GOPATH/src, so setting

export GOPATH=`pwd`

in your build.sh makes it fail. If you put your apps_api inside say ~/fakegopath/src/ and run

env GOPATH="${HOME}/fakegopath/src/" GO15VENDOREXPERIMENT="1" go build .

it should work.
