      public class Sync
      extends AbstractCopyTask

  Synchronizes the contents of a destination directory with some source directories and files.

  This task is like the `Copy` task, except the destination directory will only contain the files copied. All files that exist in the destination directory will be deleted before copying files, unless a `preserve(Action)` is specified.

  Examples:

       // Sync can be used like a Copy task
       // See the Copy documentation for more examples
       task syncDependencies(type: Sync) {
           from 'my/shared/dependencyDir'
           into 'build/deps/compile'
       }

       // You can preserve output that already exists in the
       // destination directory. Files matching the preserve
       // filter will not be deleted.
       task sync(type: Sync) {
           from 'source'
           into 'dest'
           preserve {
               include 'extraDir/**'
               include 'dir1/**'
               exclude 'dir1/extra.txt'
           }
       }

  - ### Method Detail

    - #### createCopyAction

          protected org.gradle.api.internal.file.copy.CopyAction createCopyAction()

      Specified by:
        `createCopyAction` in class `AbstractCopyTask`

    - #### createRootSpec

          protected org.gradle.api.internal.file.copy.CopySpecInternal createRootSpec()

      Overrides:
        `createRootSpec` in class `AbstractCopyTask`

    - #### getRootSpec

          public org.gradle.api.internal.file.copy.DestinationRootCopySpec getRootSpec()

      Specified by:
        `getRootSpec` in interface `org.gradle.api.internal.file.copy.CopySpecSource`
      Overrides:
        `getRootSpec` in class `AbstractCopyTask`

    - #### getDestinationDir

          @OutputDirectory
          public File getDestinationDir()

      Returns the directory to copy files into.
      Returns:
        The destination dir.

    - #### setDestinationDir

          public void setDestinationDir(File destinationDir)

      Sets the directory to copy files into. This is the same as calling `AbstractCopyTask.into(Object)` on this task.
      Parameters:
        `destinationDir` - The destination directory. Must not be null.

    - #### getPreserve

          @Internal
          @Incubating
          public PatternFilterable getPreserve()

      Returns the filter that defines which files to preserve in the destination directory.
      Returns:
        the filter defining the files to preserve
      See Also:
        `getDestinationDir()`

    - #### preserve

          @Incubating
          public Sync preserve(Action<? super PatternFilterable> action)

      Configures the filter that defines which files to preserve in the destination directory.
      Parameters:
        `action` - Action for configuring the preserve filter
      Returns:
        this
