Description

This Jira ticket is inspired by GitHub issue: https://github.com/mojohaus/properties-maven-plugin/issues/39

The problem: there are some plugins online, like properties-maven-plugin for instance, that load maven properties from different locations. And developers often want to use such plugins like this:

1. Load some varaibles from file
2. Dynamically apply this varaibles as a plugin configuration parameter

The problem is that the DOM of pm.xml seems to be parsed before any plugin took place which is perfectly reasonable to assume. But I think we should improve on that: Can we re-evaluate tags values when it is actaully used?

What do I mean - let's say we declare properties-maven-plugin that laod proeprties at validate stage. After that we have an assembly-maven-plugin at package stage, which assembles the tar archive. The name of the archive is detemrmined in the <configuration> by tar.archive.name variable. But currently it does not matter if this variable was loaded by proeprties-maven-plugin - we evaluated pom.xml DOM before any build. The point of this Jira ticket is to change that and, if  tar.archive.name was declared in the file loaded by properties-maven-plugin to be re-evaluated when assembly-maven-plugin actually gets executed
