Maven build jar for parent module

jar, maven, module, parent

Solution

In Maven tree node is always a project with type `pom` (project tree definition). Module with type `jar` is always a tree leaf (generated product). Tree node are named aggregator projects and requires 'pom' as packaging.

Your project should look like this (3-level as you ask)

+ Project parent (POM)
  + Abstract module (JAR) // bunch of abstract classes which are used by children
  + Implementation Modules (POM)
    + Module A (JAR) // depend on abstract classes from Abstract
    + Module B (JAR) // depend on abstract classes from Abstract
    + Module C (JAR) // depend on abstract classes from Abstract

Abstract Module is configured as dependency in Module A, B and C.

Problem

I have the following structure in the project: ``` Project - |- Parent // bunch of abstract classes which are used by children |- child_A // depend on abstract classes from Parent |- child_B // depend on abstract classes from Parent |- child_C // depend on abstract classes from Parent ``` I would like to build jars both for the parent and children as well. So I would end up with parent.jar, child_*.jar. How can I do this in maven?
