x/vgo: unknown legacy config file ...\Gopkg.lock

What version of Go are you using (go version)?

go 1.10
vgo b1062e5e

Does this issue reproduce with the latest release?

Just updated to vgo b1062e5e and retested, problem still occurs.

What operating system and processor architecture are you using (go env)?

What did you do?

I have a project (not public, sorry) with dependencies managed by dep. I tried to convert it to vgo using vgo build.

The Gopkg.toml looks like this:

[[constraint]]
  name = "github.com/pkg/errors"
  version = "0.8.0"

[[constraint]]
  name = "github.com/satori/go.uuid"
  version = "1.1.0"

[[constraint]]
  name = "github.com/go-test/deep"
  version = "1.0.0"

The Gopkg.lock looks like this:

# This file is autogenerated, do not edit; changes may be undone by the next 'dep ensure'.


[[projects]]
  name = "github.com/go-test/deep"
  packages = ["."]
  revision = "9898238679c264cfb10411539f14a0553dc8b295"
  version = "v1.0.0"

[[projects]]
  name = "github.com/pkg/errors"
  packages = ["."]
  revision = "645ef00459ed84a119197bfb8d8205042c6df63d"
  version = "v0.8.0"

[[projects]]
  name = "github.com/satori/go.uuid"
  packages = ["."]
  revision = "879c5887cd475cd7864858769793b2ceb0d44feb"
  version = "v1.1.0"

[solve-meta]
  analyzer-name = "dep"
  analyzer-version = 1
  inputs-digest = "a8c99240f47ae4392b67053fc7e69f386e8640fb60b0b9792c5a7127bc73b064"
  solver-name = "gps-cdcl"
  solver-version = 1

What did you expect to see?

A generated go.mod replicating the dependencies from Gopkg.toml.

What did you see instead?

An error from vgo:

vgo: unknown legacy config file C:\Users\gordon.tyler\go\src\myproject\Gopkg.lock

Change https://golang.org/cl/110117 mentions this issue: cmd/go/internal/modfetch: fix legacy config file path parsed failed

Verified, works for me.
