gopls: Unable to build on vscode

[byteshiva]

What did you do?

I'm trying to build go source file using gopls on Microsoft vscode. Instead of executing go build on the specific file, it fails to execute the build command.
note:
I'm using go version manager to maintain its different go runtimes.

Here is the code.
https://play.golang.com/p/HhCLwAZhaBk

What did you expect to see?

It should build a specific file.

What did you see instead?

It's not building the specific file.

gopls does not execute builds in VS Code, so I think your issue should be moved to the https://github.com/microsoft/vscode-go repository.

Thanks I'll move this bug to vscode-go.

Are there any timeline when the buildOnSave would be made available on gopls

There currently isn't any plan for this feature, but this is something we might be able to do via a CodeLens. Closing this issue for now, as it is not yet a planned feature, but we will likely investigate this in the future.
