Intellisense not working for imported packages when using dep

Setup

I am using: OS: windows 10 vs code: 1.30.1 go version: go1.11.4 windows/amd64 (and go1.11.1 linux/amd64 on WSL)

go env on windows:

PS C:\Users\fab> go env

Problem

Continuing issue #https://github.com/Microsoft/vscode-go/issues/2182

tl;dr: While using dep I am not receiving any intellisense for imported packages.

local packages:

But after inserting the function manually, peek for definition works fine:

Also all necessary .a files exist:

for windows_amd64:

fab@fab-surfacePro:/mnt/c/go-dev/pkg/windows_amd64/mc2innovations.visualstudio.com$ find CP_BC_Chaincodes/ -maxdepth 1
CP_BC_Chaincodes/
CP_BC_Chaincodes/errorUtils.a
CP_BC_Chaincodes/eventUtils.a
CP_BC_Chaincodes/loggerUtils.a
CP_BC_Chaincodes/tokenUtils.a
CP_BC_Chaincodes/validatorUtils.a
CP_BC_Chaincodes/vendor

for linux_amd64:

fab@fab-surfacePro:/mnt/c/go-dev/pkg/linux_amd64/mc2innovations.visualstudio.com$ find CP_BC_Chaincodes/ -maxdepth 1
CP_BC_Chaincodes/
CP_BC_Chaincodes/errorUtils.a
CP_BC_Chaincodes/eventUtils.a
CP_BC_Chaincodes/loggerUtils.a
CP_BC_Chaincodes/tokenUtils.a
CP_BC_Chaincodes/validatorUtils.a
CP_BC_Chaincodes/vendor

And just to understand it better I would like to ask again: When running vs code on windows, vs code is using GOPATH/bin/gocode.exe, right? And does gocode.exe searches only for the .a files in GOPATH/pkg/windows_amd64 or also in GOPATH/pkg/linux_amd64?

Yes, on Windows, VSCode-Go runs the executable $GOPATH/bin/gocode.exe, but that's just because that's how executables are named on Windows. I believe that if you run go install for gocode on Windows, gocode.exe will be built.

Also, gocode only looks in the $GOPATH/pkg folder for the architecture that you are on. So on, Windows, it will be $GOPATH/pkg/windows_amd64, and on Ubuntu, it will be $GOPATH/pkg/linux_amd64. Just to check, which architecture is the problem occurring on - both? What flags, if any, are you passing into gocode?

Ok thx for the explanation. I feared so because thats what led me to the problem with building \github.com\miekg\pkcs11 on windows. Which is kinda difficult because I need to get libtools working on windows - but I will think about this later :)

Just to check, which architecture is the problem occurring on - both?

Actually I tried it only on windows because thats where I run VScode. Ubuntu I use only as WSL on windows - so no gui here. Do you know of another option how I could try this on ubuntu wsl?

What flags, if any, are you passing into gocode?

I left all by default, so I guess I am passing none. But how could I verify this when using gocode in VScode?

Closing this issue, as this repository is in maintenance mode. For a better Go autocompletion experience, I would suggest using gopls.

It also seems that https://github.com/mdempsky/gocode/issues/84 would be relevant here.
