Error: duplicate new variable declaration breaks go install

[inertica]

Building from the latest master branch produces an error:

/go/src/github.com/go-oauth2/oauth2/server/server.go:243:6: no new variables on left side of :=

The failing build command on the build pipeline:

go get -t ./...     && go vet ./...     && go test ./...     && go install ./cmd/...

Can reproduce the error on local development by updating the package and using Go version 1.14.10 by running only go install ./cmd/... command.

such mistake should have caught during compile time itself, does that mean it's been released without testing properly?
