  In the next example, we demonstrate the use of `AntBuilder` to copy a list of files

  Another example would be iterating over a list of files matching a specific pattern:

  Or execute a JUnit test:

  We can even go further by compiling and executing a Java file directly from Groovy:
  
  [source,groovy]

  It is worth mentionning that `AntBuilder` is included in http://gradle.org/[Gradle], so you can use it in Gradle
