gopls and current path

[pierrre]

Go version: go1.12.6 linux/amd64
VSCode version: 1.35.1
VSCode Go version: 0.11.0
Gopls version: the latest available at this time (da514acc4774e511ba0c2955844e655a5b20938c, I've installed it through vscode-go)

The language server doesn't work at all for me.
For each interaction with the editor, I see a lot of errors in the "gopls" logs:

I can reproduce the issue using the command line (call gopls manually).
If my current directory is not inside the project, I get the same error message.
If my current directory is inside the current project, it works fine.

My VSCode config:

I've found a workaround.

In my current workflow, I'm opening the directory /home/pierre/gosrc (which is NOT my GOPATH) in my vscode workspace.
When I try to use gopls, it fails.

However, if I open a new window, containing only 1 single project, it works !
So I guess that vscode-go runs the commands relatively to the root directory of the workspace.

But I can't work like this, I need to have quick access to all my projects.

PS: maybe there is an acceptable workflow:

• open a new vscode workspace
• add each project as a root directory in my workspace

@pierrre: If you are using modules, you will have to use the approach of multiple workspace folders. The editor notifies gopls where the module root is, so if you open a directory above the module root, gopls will not work correctly.

OK thank you, I'm closing this issue, and will follow golang/go#32394
