Dep: Gopkg.toml override source question

[xcorpio]

I am build a gRpc helloword client with the import

"golang.org/x/net/context"
"google.golang.org/grpc"

I can't access these two repositories directly. So i make my Gopkg.toml file like this:

[[override]]
  name = "golang.org/x/net"
  source = "https://github.com/golang/net.git"

[[override]]
  name = "google.golang.org/grpc"
  source = "https://github.com/grpc/grpc-go.git"

What version of dep are you using (dep version)?

dep: stable 0.3.0 (bottled), HEAD

What dep command did you run?

[sdboyer]

hi, welcome! let's look a little more closely at those errors:

unable to deduce repository and source type for "golang.org/x/net/context": unable to read metadata: unable to fetch raw metadata: failed HTTP request to URL "http://golang.org/x/net/context?go-get=1": Get http://golang.org/x/net/context?go-get=1: dial tcp 61.91.161.217:80: i/o timeout

my guess is that you're running into the GFW.

as for why we still have to do those deductions and reach out even when the source field is specified, this is an increasingly common concern. the reasons why we still do it are kinda complicated, and we can probably get around it - see #860.

(closing this, as we can't do anything directly about the GFW, and we've got issues already for the latter problem.)

my guess is that you're running into the GFW.
