java.util.MissingResourceException：找不到基本名称消息包，语言环境en_US Floreant POS

Question

I have downloaded the FLoreant POS open source code, using mvn clean install it got build successfully. But when I am trying to run the application its not able to read the messages.properties file even though everything is in classpath below is the structure of project and classpath snapshot. not getting any clue why input Stream is coming as null in code

private static class ResourceControl extends ResourceBundle.Control {
        @Override
        public ResourceBundle newBundle(String baseName, Locale locale, String format, ClassLoader loader, boolean reload) throws IllegalAccessException,
                InstantiationException, IOException {
            String bundlename = toBundleName(baseName, locale);
            String resName = toResourceName(bundlename, "properties"); //$NON-NLS-1$
            InputStream stream = loader.getResourceAsStream(resName);
            return new PropertyResourceBundle(new InputStreamReader(stream, "UTF-8")); //$NON-NLS-1$
        }

    }

Just copy "i18n" directory from src to target/floreantpos-bin directory. Run your application from target/floreantpos-bin directory using

 java -jar floreantpos.jar
