[Groovy] Using AntBuilder to copy a directory

def ant = new AntBuilder()

ant.copy(todir:"backup" ){

fileset(dir:"images" )

}

// build.xml

<project name="test" basedir="." >

<target name="backupImages" >

<copy todir="backup" >

<fileset dir="images" />

</copy>

</target>

</project>

To copy an entire directory of files (including subdirectories), you need to use a nested fileset. Notice that the nested XML shows up as a nested closure in Groovy.

Groovy这种语法真的是挺特别的
