Warning during add api about missing package

Bug Report

When adding a new api via

operator-sdk add api --api-version=hello.k8spatterns.io/v1alpha1 --kind=Hello

on a freshly created project, I get the following output:

INFO[0000] Generating api version hello.k8spatterns.io/v1alpha1 for kind Hello.

It looks like it succeeded and the directory pkg/apis/hello has been created eventually:

ls pkg/apis/hello
v1alpha1

However, the warning is a bit disturbing. Also I was wondering why I was ask for my GitHub credentials during the process (looks like a read-write checkout of some GitHub repo)

Here the full output with --verbose:

operator-sdk add api --api-version=hello.k8spatterns.io/v1alpha1 --kind=Hello --verbose

Environment

• operator-sdk version:

operator-sdk version: v0.8.1, commit: 33b3bfe

• go version:

go version go1.12.5 darwin/amd64

[joelanford]

The question about the warnings has come up a couple of times. See this PR for details: #1401

I'm not sure about the GitHub credentials dialog, but my guess would be that it happens as part of the compilation of the generator binaries when go build is executed with Go modules enabled. Does the dialog come up around the following lines?

Fetching https://github.com?go-get=1
Parsing meta tags from https://github.com?go-get=1 (status code 200)

@rhuss: @joelanford is correct, go/build package parsing causes this error.

This issue relates to #1502. For a temporary fix, try the following before running operator-sdk add api:

$ mkdir -p pkg/apis/hello && echo "package hello" > pkg/apis/hello/stub.go

PR #1401 should fix this once merged.
