public class SignJar
extends Task

Signs jar or zip files with the javasign command line tool. The tool detailed dependency checking: files are only signed if they are not signed. The `signjar` attribute can point to the file to generate; if this file exists then its modification date is used as a cue as to whether to resign any JAR file.
Note: Requires Java 1.2 or later.

Since:
  Ant 1.1
