    public static String getDeploymentFilePath() {
        String configFilePath = System.getProperty(Constants.DEPLOYMENT_CONFIG_FILE_PATH);
        if (StringUtils.isEmpty(configFilePath)) {
            configFilePath = Paths.get(System.getProperty(Constants.CARBON_CONFIG_DIR_PATH),
                             Constants.DEPLOYMENT_TOML_FILE).toString();
