Go importing vendor dependencies issue when building a Go 1.7 project using govendor, dh-make-golang

I've been looking into building a go project into a debian package.

I've looked into dh-make-golang and I have a nice and shiny debian folder set up in my repository. When I try to use gbp buildpackage --git-pbuilder though it errors out due to all of my dependencies not being found. It seems that dh-make-golang ignores the vendor folder when it copies everything from my project's git repository, and I use govendor so all of my dependencies are in there.

How can I resolve this dependency issue and build the project as a .deb package properly? For reference, the error I am getting is:

src/github.com/project/project/project.go:15:2: cannot find package "google.golang.org/grpc/grpclog" in any of:
/usr/lib/go-1.7/src/google.golang.org/grpc/grpclog (from $GOROOT)
/tmp/project/obj-x86_64-linux-gnu/src/google.golang.org/grpc/grpclog (from $GOPATH)


Issue was a bug in dh-make-golang regarding importing vendor dependencies. It was just fixed today.

Take a look at goxc - it can do this for you!

You simply need to add a .goxc.json to the root of your directory, that looks like this

{
	"AppName": "my_app",
	"ArtifactsDest": "downloads",
	"Tasks": [
		"interpolate-source"
		"deb",
	],
	"BuildConstraints": "linux,amd64 windows,amd64 darwin,amd64 linux,arm",
	"ResourcesInclude": "INSTALL*,README*,LICENSE*,config/*,static/*,templates/*",
	"PackageVersion": "0.9.3",
	"TaskSettings": {
		"deb": {
			"metadata": {
				"description": "my app",
				"maintainer": "me",
				"maintainer-email": "me@example.com"
			},
			"metadata-deb": {
				"Homepage": "https://example.com"
			},
			"other-mapped-files": {
				"/": "debian/",
				"/usr/share/something/static": "static/",
				"/usr/share/something/templates": "templates/"
			}
		}
	},
	"ConfigVersion": "0.9"
}

Then run goxc and it'll do all the work for you.
