如何使供应商与Google App Engine一起使用？

Question

I am trying to introduce Go vendoring (storing dependencies in a folder called vendor) 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:

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"

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

Answer 1

I managed to resolve this error using govendor instead of Godeps. The root cause appears to have been that vendored references with their own vendored references was not resolved correctly by Godeps.

The answer provided by Su-Au Hwang is also correct - you do have to keep app.yaml separate from your source.
