The Maven team is pleased to announce the Ant plugin 1.5 release!

http://maven.apache.org/reference/plugins/ant/

The Maven Ant plugin is a plugin that generates a simple Ant build file from
the project.xml file.

Fixed in this version

o Absolute paths were being generated in build.xml. Relative paths are now output

Note that this plugin has been tested with Maven 1.0 rc1. Using it with
another version of Maven is at your own risk! :-)

You can download and install the Ant plugin by using

maven -DgroupId=maven -DartifactId=maven-ant-plugin -Dversion=1.5 plugin:download

Have fun!
