Returns:
The arguments required to construct this bean/**

Variation of the BeanFactory.build(BeanContext, BeanDefinition) method that allows passing the values necessary for successful bean construction. 
Params:
resolutionContext –  The BeanResolutionContext
context –  The BeanContext
definition –  The BeanDefinition
requiredArgumentValues – The required arguments values. The keys should match the names of the arguments returned by getRequiredArguments()
Throws:
BeanInstantiationException – If the bean cannot be instantiated for the arguments supplied
Returns:
