I was running @Theory examples and found the following code cannot pass compilation.

public static class BetweenSupplier extends ParameterSupplier {
         @Override
         public List<PotentialAssignment> getValueSources(ParameterSignature sig) {
             List<PotentialAssignment> list = new ArrayList<PotentialAssignment>();
             Between annotation = (Between) sig.getSupplierAnnotation(); // cannot resolve method

             for (int i = annotation.first(); i <= annotation.last(); i++)
                 list.add(PotentialAssignment.forValue("ints", i));
             return list;
         }
}

So tell us what the compiler says. I was using it without any problem.

cannot resolve method 'getSupplierAnnotation()'.
