In the upcoming Groovy (jsr-02) release (in a month or so), Jeremy
Rayner created a groovy Ant task, and I've patched it to be
Maven-friendly. So you should be able to do what you want with Maven +
Groovy.

You'll be able to use Groovy in your maven.xml like so:

<?xml version="1.0" encoding="UTF-8"?>
<project default="groovy" xmlns:ant="jelly:ant"> 
  <goal name="groovy">
    <ant:taskdef name="groovy"
classname="org.codehaus.groovy.ant.Groovy"
classpathref="maven.dependency.classpath"/>
    <ant:groovy>
    	println pom.eachPropertyName{ println it }
    	println pom.build.souceDirectory
    </ant:groovy>
  </goal>
</project>

You'll have to add Groovy in your dependencies:

    <dependency>
      <groupId>groovy</groupId>
      <artifactId>groovy-all</artifactId>
      <version>1.0-jsr-02-SNAPSHOT</version>
      <properties>
        <classloader>root</classloader>
      </properties>
    </dependency>

If you build Groovy from sources and install that artifact in your
local repo, you'll be able to use that Ant task.

I've just added the pom in the context, tell me if there are other
properties I'd need to bind in the context. Thanks in advance for
that.
