How to copy files in Groovy

If you are doing this in code, just use something like:

new File('copy.bin').bytes = new File('orig.bin').bytes

If this is for build-related code, this would also work, or use the Ant builder.

Note, if you are sure the files are textual you can use .text rather than .bytes.

If you have Java 7, I would definitely go with

Path source = ...
Path target = ...
Files.copy(source, target)

With the java.nio.file.Path class, it can work with symbolic and hard links. From java.nio.file.Files:

This class consists exclusively of static methods that operate on files, directories, or other types of files. In most cases, the methods defined here will delegate to the associated file system provider to perform the file operations.

My second option would be the ant task with AntBuilder.
