      @DisableCachingByDefault(because="Not made cacheable, yet")
      public abstract class Sign
      extends DefaultTask
      implements SignatureSpec

  A task for creating digital signature files for one or more; tasks, files, publishable artifacts or configurations.

  The task produces `Signature`

  objects that are publishable artifacts and can be assigned to another configuration.

  The signature objects are created with defaults and using this tasks signatory and signature type.
