[forge-issues] [JBoss JIRA] (FORGE-2232) Documenting how to create and test a command that creates Java code

Documenting how to create and test a command that creates Java code ------------------------------------------------------------------- Key: FORGE-2232 URL: https://issues.jboss.org/browse/FORGE-2232 Project: Forge Issue Type: Sub-task Components: Documentation Affects Versions: 2.14.0.Final Reporter: Antonio Goncalves Assignee: George Gastaldi Fix For: 2.x Future The idea is to document commands that create new code ({{new}} commands). There are several level of complexity and we should go step by step : 1. A command to create a [new constraint payload|FORGE-1620] is quite simple. It only generates Java code to a specific directory 2. A command to create a [new package info|FORGE-2071] is a bit tricker because the generate Java code is not a class per-se 3. A command to create a [new constraint validator|FORGE-1618] have several parameters that can be used ({{type}} and {{targetConstraint}}). The case of the [JPA Listener|FORGE-2093] is also important because the command taks a choice of parameters ({{POST_UPDATE}}, {{PRE_PERSIST}}...)
