In this example, the `moveFile` task uses the `Copy` task type to specify the source and destination directories.
Inside the `doLast` closure, it uses `File.renameTo()` to move the file from the source directory to the destination directory:

[source,groovy]
----
task moveFile {
    doLast {
        def sourceFile = file('source.txt')
        def destFile = file('destination/new_name.txt')
