[groovy-user] AntBuilder and the Maven Ant Task

I am wondering if this is a new feature requirement for AntBuilder or I
am just missing something obvious.

I have a target in a Gant script:

target ( doPrint : 'Print the dependencies from the POM.' ) {
  echo ( message : 'User is ${user.name}' )
  println ( ant.project.properties.'user.name' )
  "antlib:org.apache.maven.artifact.ant:pom" ( id : 'project' , file :
'pom.xml' )
  echo ( message : '${project.version}' )
  println ( ant.project.properties.'project.version' )
}

the output is:

|> gant -f printDependencies.gant
     [echo] User is russel
russel
     [echo] 1.5.0-SNAPSHOT
null
|>

So accessing properties held in Ant via the AntBuilder generally is
working fine.  Clearly accessing the properties generated by executing
the POM reader is not working.

Anyone any ideas?

Thanks.
