vim-go: finished loading packages

If I edit go.mod and remove the patch number from the version (1.22.1 to 1.22 in my case), then it works without errors. This relates, I think, to the closed issue golang/vscode-go#3276

@tvendelin Thanks for the bug! I see that you are using go1.22.1 which I think should not have this issue. Can you check what version of go gopls is built with by running $ gopls -v version? Thank you!

I am trying to investigate why this issue is coming up so frequently in the last week, what changed that made you encounter this issue now? Did you recently update go versions?

[tvendelin]

@suzmue "Waiting for info"?

Your question is already answered in my bug report. I've also described a workaround. From what I see, a go.mod generated by go mod init disagree with gopls about the version format.

[seankhliao]

we asked for the output of a specific command, which you have not provided.

[suzmue]

Assuming that the gopls you are running was built with an older go version, you will need to rebuild gopls with go1.21 or newer:

$ go install golang.org/x/tools/gopls@latest

You can verify that gopls has the new version by:

$ gopls -v version
