@DisableCachingByDefault(because="Not worth caching") public abstract 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'
         }
     }

  - ### 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:

  - ### getDestinationDir

    @OutputDirectory public File getDestinationDir()
    Returns the directory to copy files into.
    Returns:

    See Also:
      - `getDestinationDir()`

  - ### preserve

    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
    See Also:
      - `getDestinationDir()`

  - ### getDeleter
