How to debug geth with goland?

I would like to be able to debug through Geth's Go code - using Goland.

It looks to me as if the entry point for Geth is main.go, however, when I try to run this I get the following errors:

GOROOT=/usr/local/Cellar/go/1.11/libexec #gosetup
GOPATH=/Users/codet/go #gosetup
/usr/local/Cellar/go/1.11/libexec/bin/go build -o /private/var/folders/6t/tdn_s_2x2rx1scn774cwvlph0000gn/T/___geth_go -gcflags "all=-N -l" /Users/codet/go/src/github.com/ethereum/go-ethereum/cmd/geth/main.go #gosetup

cmd/geth/main.go:186:3: too many errors

Compilation finished with exit code 2

I add debug point to function main, but it didn't work.

func main() {
    if err := app.Run(os.Args); err != nil {
        fmt.Fprintln(os.Stderr, err)
        os.Exit(1)
    }
}

Dude, try this command go build -x path-to-go-ethereum/cmd/geth/*go, you will see what happens with flag -x. Should compile the package instead. In goland, right click the geth folder, just choose run->go bulid, you will get what you expect.
