为什么找不到我的供应库？

package vpc_app/unit_test.go:

import (
    "github.com/my-org/my-library/http"
)
...

package github.com/my-org/my-library/http/http.go:

package http
...

Problem:

When I run go test ./... I get this error:

vendor/github.com/my-org/my-library/url_checker.go:7:2: cannot find package "github.com/my-org/my-library/http" in any of:
    /usr/local/go/src/github.com/my-org/my-library/http (from $GOROOT)
    /Users/josh/go/src/github.com/my-org/my-library/http (from $GOPATH)

Question:

I'm using go 1.6, but it doesn't seem to look in my vendor directory to find the package. Any ideas on why that might be?

Update #1: As requested, here's my go env output:

OARCH="amd64"
GOBIN=""
GOEXE=""
GOHOSTARCH="amd64"
GOHOSTOS="darwin"
GOOS="darwin"
GOPATH="/Users/josh/go"
GORACE=""
GOROOT="/usr/local/go"
GOTOOLDIR="/usr/local/go/pkg/tool/darwin_amd64"
GO15VENDOREXPERIMENT="1"
CC="clang"
GOGCCFLAGS="-fPIC -m64 -pthread -fno-caret-diagnostics -Qunused-arguments -fmessage-length=0 -fno-common"
CXX="clang++"
CGO_ENABLED="1"

My repo wasn't located in the GOPATH. Moving it to $GOPATH/src/github.com/my-org/my-library did the trick.

That error is originating from vendor/github.com/my-org/my-library/url_checker.go which is in your vendor folder.

It looks like it is finding the vendor folder, but the issue is due to an import statement in vendor/github.com/my-org/my-library/url_checker.go on line 7

Investigating to see if there is an issue with recursive dependencies with vendor folders.

Just to be clear can you provide the output of go env?
