vendor folder not used with 'go build'

Question

I'm using go-1.7 in MacOS Sierra.

My project is inside my $GOPATH/src folder and has a vendor folder inside with all its dependencies.

and I'm using the dependencies like this inside my code:

import (
"github.com/google/go-github/github"
)

Now if I run go build i get the message that all my dependencies I use could not be found inside the $GOROOT and $GOPATH on the other and adding "vendor" to my code is working:

import (
"vendor/github.com/google/go-github/github"
)

But as far as I understood it should be possible to to like in the first code snipped.

ah FYI there are no symlinks etc.

From go 1.12+ go modules is the new way of handling dependencies.

• To fix dependency version go mod init
• To bring modules in vendor folder go mod vendor
• To build from the vendor directory go build -mod vendor -o output
