VersionProperty

Introduction

Version Property is an ant task. The task fills 4 ant properties named spec, impl, patch and string with version information. This information is loaded from a class file. So you can define static int fields in a class which are accessible from ant scripts. The properties are get a prefix the property ${version.string} holds e.g. 1.2.0
Prerequsites:
1. the class has to have a constructor that takes no parameters, so that the task can instanciate the class
2. the fields have to be of the type "int"
