VenGard ERP description:  VenGard ERP has 20 module mentioned this figure.  One module depends on other module. Like: Sales depends three module on inventory, order management, accounting.

So, My JAVA EE EAR structure is:  Every module is  EJB jar . for building project we use maven . for one module , one programmer is responsible.

Problem is: Development time problem

1. Building time related problem :  When occur a business problem (changes) in one module , we need to build all module . it takes lot of time (5 mins) for building EAR File in development time . in some moment it is very critical .

1. Building time Error : when a  programmer try to fixing a bug for a particular module (inventory), he need to  build all module . so, if occur any building error  from other module(sales)    he cannot  identified easily  from other module bug  in EAR file building time .

My Expectation : when problems comes from a particular module , we want to build and test  only this module not all  module , it save lot of time and hassle .

We want to build all modules only one time (release, regression test).

pls help me ?
