Invalid with Go and Crystal

[yanecc]

I edited the user settings file as below.

{
  "build_schemas" : {
    "go" : {
      "shell_cmd" : "go run ${file}",
      "input_start" : "/* input",
      "input_end" : "*/"
    },
    "cr" : {
      "shell_cmd" : "crystal run ${file}",
      "input_start" : "%( input",
      "input_end" : ")"
    }
  }
}

It only prompts "Saved ...", "Build finished" in the status bar at the bottom. Where is the problem?
