Error with go module and git submodules

[pascencio]

Hi guys,

I have some troubles with the extension and git submodules.

What version of Go, VS Code & VS Code Go extension are you using?

• Run go version to get version of Go
  • go1.14.5 linux/amd64
• Run code -v or code-insiders -v to get version of VS Code or VS Code Insiders
  • 1.48.0-insider
• Check your installed extensions to get the version of the VS Code Go extension
  • v0.15.2
• Run go env to get the go development environment details

Describe the bug

Problem

I have a project with two components:

1. Backend with golang using go modules.
2. Frontend with vue

Both components are git submodules in a parent repository. When I open the project with both submodules I have the following issues:

1. Module dependencies are not imported (autocompleteUnimportedPackages)
2. Error with packages already imported

Opening directly submodule resolves the issue.

Behavior expected

I expect same behavior with git submodules and simple git project.

Steps to reproduce the behavior:

1. Clone a project with git submodules (with golang modules inside).
2. Init and update submodules.
3. Open main.go file
4. See errors in packages imported already declared in go.mod file.

Screenshots or recordings

@pascencio It looks like this is another way of creating a repo setup that is currently not supported by gopls. See #275 - currently gopls (the default language server used by "go.useLanguageServer": true) requires the directory with go.mod to be the root workspace.

Currently suggested workaround is to add the sub directory that contains go.mod file as a workspace folder (https://code.visualstudio.com/docs/editor/multi-root-workspaces).

@hyangah I will try to use the workaround mentioned by you. Thanks!

@hyangah You workaround works perfectly.

This issue is related with the extension? or I must report this to the gopls team?

To me is enough with your answer, thanks again!

This is a gopls issue that will be addressed in future versions. Glad you got it working!
