Enhance support for go get inside the plugin #2053
Description
In order for the plugin to properly download all the dependencies of a package, it should execute the go get update with something like this go get <package-name>/... which will traverse the whole package after downloading and get the dependencies.
Also, it could be useful to add the -t switch to go get so that the test dependencies are also downloaded.
go get has a -v switch which allows it to display what happens when it's downloading the package. For example:
go get -v -u github.com/koding/kite/...

I wonder if the plugin could use that to display the name of the downloaded packages while running the quickfix.
Finally, should the plugin provide a way to run go get -u on a package to update it
