Reflections Library , unable to find any classes within my package

I am attempting to use the reflections library to get access to classes inside a package in my project. As per suggestions from the question below.

Can you find all classes in a package using reflection?

When running my method, size() on my set 0 is shown.

 List<ClassLoader> classLoadersList = new LinkedList<ClassLoader>();
       classLoadersList.add(ClasspathHelper.contextClassLoader());
       classLoadersList.add(ClasspathHelper.staticClassLoader());

        Reflections reflections = new Reflections(new ConfigurationBuilder()
                .setScanners(new SubTypesScanner(false), new ResourcesScanner())
                .setUrls(ClasspathHelper.forClassLoader(classLoadersList.toArray(new ClassLoader[0])))            
         .filterInputsBy(newFilterBuilder().include(FilterBuilder.prefix("com.ruperts.java.Commands"))));


        Set<Class<?>> classes = reflections.getSubTypesOf(Object.class);

        System.out.println(classes.size());

I also tried setting the prefix to "" as per comment in other questions - still shows as no classes were found.

if anyone wonders a the simplest way to get the default package is having the prefix be an empty String -> "".

Is the issue with my package name?
