Problem Statement

Project Families

There are maven project families.

There are 2 ways to release them.

1. maven-release-plugin for Multi-module Project

• requires tightly-coupled parent/child <module/>
• provides single monolithic release
• can be done by maven alone
• all-or-none release mode
• top-down, linear approach

2. maven-cascade-release-plugin

• requires loosely-coupled parent/child <module/>
• provides incremental/partial release
• requires jenkins + maven install
• any-part-of-a-tree release mode.
• bottom-up, recursive approach

Also some use cases:

Visually

For this project family:
https://github.com/barchart/barchart-jenkins-tester

how many steps and how much time will it take to release a "zoo" when change is made to an "ant"

how about the "ecosystem"
