With HEAD and all previous versions, there are panics.

Here's a possible stack trace:

@wgliang Looks like there is a typo at line 40 in main.go.
Perhaps you meant err != nil instead of err == nil.

$ ag -A 2 -B 2 'project path is invalid'
main.go
41-		_, err := os.Stat(*project)
42-		if err == nil {
43:			log.Fatal("project path is invalid")
44-		}
45-	}

Sorry, this is my negligence.
When I push it finish, I regret it.
