Vim-go: GoDef doesn't work within go-module directory while passing in Package-Scoped-Var(defined and refered in different files)

[fly-potato-100]

What did you do? (required: The issue will be closed when not provided)

1. mkdir demo1;cd demo1

2. go mod init demo1

3. echo 'package main
   import "fmt"
   func main() {
   fmt.Println(Str)
   }' > main.go

4. echo 'package main
   var Str = "hello world,demo1!"' > def.go

5. vim main.go

6. PRESS gd or CTRL+] or :GoDef on the Str identifier

What did you expect to happen?

I expected that vim would jump to _def.go_ and move cursor to line 2.
I have noticed that go-module support has been released since v1.19

What happened instead?

Have you run :GoInstallBinaries? If it has been a while since you did, then please run :GoUpdateBinaries. Finally, if all the binaries are updated, try setting g:go_def_mode to 'gopls'.

Setting g:go_def_mode to 'gopls' works! thx!
But my project which was placed OUTSIDE GOPATH failed to :GoDef with an error:
vim-go: no object for ident XXX.
(I have set g:go_autodetect_gopath = 1 before)
I wonder maybe they conflict with each other??

I have read the script of go#def#Jump and have an answer.
It seems to be my job to determine when and which go_def_mode to use.
I'm trying to configure my .vimrc to make it work as before.

gopls should work for module mode, too. Be sure there's a go.mod file available.

fwiw, I tried this with g:go_def_mod_mode='godef' and it works in both GOPATH mode and in module mode. It's only guru that has a problem in module mode, but that's to be expected, as guru is not away of modules.
