Dep ensure -v does not vendor all pkgs of dependency which is not used yet.

[prateeknayak]

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

dep:
 version     : v0.4.1
 build date  : 2018-01-27
 git hash    : 37d9ea0
 go version  : go1.9.3
 go compiler : gc
 platform    : darwin/amd64

What dep command did you run?

dep ensure -v

Warning: the following project(s) have [[constraint]] stanzas in Gopkg.toml:

  ✗  github.com/aws/aws-sdk-go

However, these projects are not direct dependencies of the current project:
they are not imported in any .go files, nor are they in the 'required' list in
Gopkg.toml. Dep only applies [[constraint]] rules to direct dependencies, **so
these rules will have no effect.**

What did you expect to see?

I expect to see the aws-sdk-go with its aws pkg vendored in.

What did you see instead?

Unfortunately, all I see is the root of the aws-sdk-go project and not the aws pkg (which is what i really want). I understand, I may not be yet importing it in my code hence dep does not resolve it for me . But at this point I am not entirely sure what pkgs out of my dependecy I would use (sure I can read the documentation) but I want to use autocomplete, Intelisense features of my IDE. For that I would require all the pkgs ahead of time wouldn't I ?

Agreed! This is a poor user experience.

When I run into this, as a workaround I turn off the prune unused packages setting, and then pick any package with go-code in it and run dep ensure -add github.com/PROJECT/RANDO/PACKAGE.

I think that when we fix the ability to add a constraint for a package without go code, that will help. We should circle back and make sure that is enough once that's in.

Dep was officially deprecated earlier this year, and the proposal to archive this repository was accepted. As such, I'm closing outstanding issues before archiving the repository. For any further comments, please use the proposal thread on the Go issue tracker. Thanks!
