I need to be able to use ReplaceRegExp task in an antrun script. However, using ReplaceRegExp requires at least one additional jar in the Ant classpath (see: http://ant.apache.org/manual/CoreTypes/regexp.html). I don't know how to get the additional jar into the Ant classpath.

In my case, I want to use the JDK1.4 regexp package, which requires ant-nodeps.jar. I have set the value of ant.regexp.regexpimpl to org.apache.tools.ant.util.regexp.Jdk14RegexpRegexp to make my choice clear to Ant.

To make my question absolutely clear, what do I need to change in this pom.xml file to make this build succeed?

                               replace="NewProperty=\1"
                               byline="true"/>
