why do I need vgo get

My workflow contemplates frequent Docker builds. In my Dockerfile, I want to be able to fetch the project dependencies in a step before copying (and building) my actual code from the host, so that Docker can cache the dependency-fetching layer and reuse it if I change the code of my module.

It would be great to have a command that just resolves imports/requires and downloads the dependencies. This is very useful for CI systems that often download package first, cache them and then move on to running tests. With current design, a CI system will not be able to cache dependencies until the tests pass.

So it would be great for vgo get or a new command to just download/cache all dependencies and exit.

Yes, we need to figure out what this means exactly.

This seems to be similar what go get ./... does, isn't it?

At least vgo get ./... was my first try to prefetch dependencies (I did it before vgo using the above construct), but it fails with the following:

FindRepo: Get https://./...?go-get=1: dial tcp: lookup .: No address associated with hostname
vgo get ./...: Get https://./...?go-get=1: dial tcp: lookup .: No address associated with hostname
