The Properties Maven Plugin is here to make life a little easier when dealing with properties. It provides goals to read and write properties from files. The Kuali version of this plugin adds support for loading properties from XML files and reading properties files from any location Spring resource loading can understand (eg classpath:myprops.properties)

There is a newer version: 2.0.1
