What you are probably facing is the design of module dependency and circular dependency. In short, the Business methods that Core needs may have to be re-factored into a 'utils' module or a 'Business-Core' module that is then accessible by both. I am only guessing here.

In addition to automating builds, a build tool like Maven also encourages such modularization and dependency. It is not unusual for a project that started off as one module to be split into 3-4 modules by the time it is done.
