go build can't find package sources

Question

I'm trying to build the teamcity prometheus exporter I found in this repo .
In the readme it instructs me to execute the following command which should build the project - docker run --rm -v "$PWD":/go/src/github.com/guidewire/teamcity_exporter -w /go/src/github.com/guidewire/teamcity_exporter -e GOOS=linux -e GOARCH=amd64 golang:1.8 go build -o bin/teamcity_exporter -v

But it fails with the following error -

teamcity_exporter.go:15:2: cannot find package "github.com/guidewire/teamcity-go-bindings" in any of:
    /go/src/github.com/guidewire/teamcity_exporter/vendor/github.com/guidewire/teamcity-go-bindings (vendor tree)

    /go/src/gopkg.in/yaml.v2 (from $GOPATH)

I've tried looking around for go package managers and using them to preinstall the packages (went over dep and govendor but both didn't seem fit to my use case) .

Also opened an issue in the github repo but there are a few other issues that didn't get any response so I'm not getting my hopes up.

I'm not that familiar with go, so I was hoping someone here might have a clue as to what I'm missing.
Thanks!

I would recommend changing go build to go get . That should fetch all the dependencies and will also build the binary and drop it into $GOPATH/bin . go build expects everything to already be in place.
