Go: x/tools/gopls: go modules in subfolders of VSCode folder are not recognized

[mback2k]

What version of Go are you using (go version)?

$ go version
go version go1.13.4 linux/amd64

golang.org/x/tools/gopls v0.3.3
    golang.org/x/tools/[email protected] h1:mTFqRDJQmpSsgDDWvbtGnSva1z9uX2XcDszSWa6DhBQ=

Does this issue reproduce with the latest release?

Unknown, as a golang 1.14 package is not available for Ubuntu Xenial.

What operating system and processor architecture are you using (go env)?

What did you do?

I am using a Go project folder structure like this:

├── npiperelay
│   ├── LICENSE
│   ├── npiperelay.go
│   ├── overlappedfile.go
│   ├── README.md
│   └── scripts
│       ├── docker-relay
│       ├── gpg-relay
│       ├── serial-relay
│       └── vmserial-connect
└── wsl-ssh-pageant
    ├── assets
    │   └── icon.ico
    ├── assets.go
    ├── azure-pipelines.yml
    ├── build.ps1
    ├── go.mod
    ├── go.sum
    ├── LICENSE
    ├── main.go
    ├── Readme.md

As you can see there is a go.mod file in the wsl-ssh-pageant project.

In Visual Studio Code I am opening the folder go-projects instead of the individual subfolders for reach project in order to quickly jump between them. You could think of it as my mono-repo-like approach with VSCode even though the individual projects are individual repos.

What did you expect to see?

I expected gopls to recognize the go.mod file in the wsl-ssh-pageant project.

What did you see instead?

Instead I am getting this error message:

You are neither in a module nor in your GOPATH. Please see https://github.com/golang/go/wiki/Modules for information on how to set up your Go project.

Thank you for filing a gopls issue! Please take a look at the Troubleshooting guide, and make sure that you have provided all of the relevant information here.

gopls currently doesn't support editing opening directories that are above a module. We will be working on fixing this for gopls/v0.5.0. A work-around is to add the root of the module to your workspace - in VS Code, that can be done by navigating to File -> Add Folder to Workspace. Sorry about the inconvenience, and we hope to have this fixed soon.

@stamblerre Thanks for your feedback, but why is this issue closed if it is not already solved yet?

[stamblerre]

We will be working on fixing this for gopls/v0.5.0.

This is an issue we are already aware of, and we have a number of issues related to it in the gopls/v0.5.0 milestone, so I closed this as a duplicate.

It’s been almost 3 months, and it’s still not fixed.
