How do I make vendoring work with Google App Engine? : <p>I am trying to introduce Go vendoring (storing dependencies in a folder called <code>vendor</code>) to an existing App Engine project. I have stored all dependencies in the vendor folder (using Godep as a helper) and it looks right, but running the application locally I get the following error: </p>

<p><code>go-app-builder: Failed parsing input: package "golang.org/x/net/context" is imported from multiple locations: "/Users/erik/go/src/github.com/xyz/abc/vendor/golang.org/x/net/context" and "/Users/erik/go/src/golang.org/x/net/context"</code></p>

<p>I believe the two locations should resolve to the same location, as Go applications should look in the <code>vendor</code> folder first. Is there a way to make Appengine understand that both dependencies are the same?</p>
