# Delete

@DisableCachingByDefault(because = "Deletion cannot be cached")
abstract class Delete : ConventionTask, DeleteSpec(source)

Deletes files or directories. Example:

    task makePretty(type: Delete) {
      delete 'uglyFolder', 'uglyFile'
      followSymlinks = true
    }

Content copied to clipboard
Be default symlinks will not be followed when deleting files. To change this behavior call setFollowSymlinks with true. On systems that do not support symlinks, this will have no effect.
