      @Deprecated public Signature(PublishArtifact toSign, SignatureSpec signatureSpec, Object... tasks)
      Deprecated.
      This constructor will be deprecated in Gradle 10.
      Creates a signature artifact for the given public artifact.

      The file to sign will be the file of the given artifact and the classifier of this signature artifact will default to the classifier of the given artifact to sign.

      The artifact to sign may change after being used as the source for this signature.

      Parameters:
      toSign - The artifact that is to be signed
      signatureSpec - The specification of how the artifact is to be signed
      tasks - The task(s) that will invoke generate() on this signature (optional)

      Deprecated.
      This constructor will be deprecated in Gradle 10.
      Creates a signature artifact for the given file, with the given classifier.
      Parameters:
      toSign - The file that is to be signed
      classifier - The classifier to assign to the signature (should match the files)

      Deprecated.
      This constructor will be deprecated in Gradle 10.
      Creates a signature artifact for the file returned by the toSign closure.

      The closures will be "evaluated" on demand whenever the value is needed (e.g. at generation time)

      Parameters:
      toSign - A closure that produces a File for the object to sign (non File return values will be used as the path to the file)
