Exporting properties from Maven to ant 

 See https://maven.apache.org/plugins/maven-antrun-plugin/usage.html 

If the Maven property you want to use is not available in an external file, you will have to redefine the property before calling ant.

<property name="maven.project.url" value="${project.url}"/>
<ant antfile="build.xml"/>
