I am using Spring Cloud GCP. It has the auto-configuration to start datastore emulator when starting the app engine devserver. However, when I read through the set up of LocalDatastoreHelper, I could see that the gcloudCommand is hard-coded. Are there any ways that I can customize the options of gcloudCommand ?

    List<String> gcloudCommand = new ArrayList<>(Arrays.asList(GCLOUD_CMD_TEXT.split(" ")));
    gcloudCommand.add(GCLOUD_CMD_PORT_FLAG + "localhost:" + getPort());
    gcloudCommand.add(CONSISTENCY_FLAG + consistency);
    gcloudCommand.add("--no-store-on-disk");
    GcloudEmulatorRunner gcloudRunner =
        new GcloudEmulatorRunner(gcloudCommand, VERSION_PREFIX, MIN_VERSION);
    if (gcdPath != null) {
      gcloudCommand.add("--data-dir=" + gcdPath.toString());
    }

I want to remove the option --not-store-on-disk and would like to change the --data-dir to my local folder.
Moreover, could you help me to find the location of the current data-dir. I do not know where it is.
Thanks
