Can you please share your gopls settings (you can find them by opening the Command Palette with Ctrl+Shift+P and selecting "Preferences: Open Settings (JSON))? Also, can you please share a more verbose gopls log by adding -rpc.trace to your go.languageServerFlags configuration? More details here: https://github.com/golang/tools/blob/master/gopls/doc/troubleshooting.md#capturing-logs.

If disable the gopls server get the cannot find package "." in: D:\git\kubernetes\vendor\k8s.io\apimachinery\pkg\types

[wu0407]

find some error that couldn't run 'go': fork/exec C:\Program Files\Go\bin\go.exe: The filename or extension is too long. in the go.mod, and find like issue therecipe/qt#657 search by google .
so uninstall the tdm-gcc, it work on the 1.18.6 tag, but not work on master.
may be update go 1.13 to go 1.15 in go.mod from 1.18 to master

becuase go auto use vendor directory if the "go" version in the main module's go.mod file is
1.14 or higher, but vendor modules.txt not contain all dependence. so set to mod model vscode, it is resolve the ploblem.

   "go.toolsEnvVars": {
    "GOFLAGS": "-mod=mod"

I don't see the inconsistent vendoring error message in your previous log, but inconsistent vendoring will certainly cause problems. You should have seen a diagnostic message with a suggested fix to run go mod vendor, but in any case, I'm glad you were able to resolve the issue.

[wu0407]

yes, i don't reproduce inconsistent vendoring error message
