x/tools/gopls: go to definition within imported modules #66827
Description
Consider a Go project with main.go looking like this:
package main
import (
"fmt"
"github.com/google/uuid"
)
func main() {
id := uuid.New()
fmt.Println(id)
}When I go to definition (F12) of uuid.New() I end up here:
func New() UUID {
return Must(NewRandom())
}So far so good.
But when I try to navigate futher to Must or NewRandom, I get a popup "No definition found...".
Whereas if I navigate to fmt.Println, I can navigate further into Fprintln, doPrintln, writeByte, etc.
Why is this difference in behavior between Go SDK packages and imported modules?
Shouldn't I be able to navigate within modules the same way I do in my own code and the Go SDK?
gopls version: v0.15.2
go version: 1.22
