## Class SignJar

- - org.apache.tools.ant.ProjectComponent
  - - org.apache.tools.ant.Task
    - - org.apache.tools.ant.taskdefs.AbstractJarSignerTask
      - - org.apache.tools.ant.taskdefs.SignJar

- All Implemented Interfaces:
    java.lang.Cloneable

      public class SignJar
      extends AbstractJarSignerTask

  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. Timestamp driven signing is based on the unstable and inadequately documented information in the Java1.5 docs
  Since:
    Ant 1.1

    beta documentation

      Compare a jar file with its corresponding signed jar. The logic for this is complex, and best explained in the source itself. Essentially if either file doesn't exist, or the destfile has an out of date timestamp, then the return value is false.

      If we are signing ourself, the check `isSigned(File)` is used to trigger the process.

      Parameters:
        `jarFile` - the unsigned jar file
        `signedjarFile` - the result signed jar file
      Returns:
        true if the signedjarFile is considered up to date

    - #### isSigned

          protected boolean isSigned(java.io.File file)

      test for a file being signed, by looking for a signature in the META-INF directory with our alias/sigfile.
      Parameters:
        `file` - the file to be checked
      Returns:
        true if the file is signed
      See Also:
        `IsSigned.isSigned(File, String)`

    - #### setPreserveLastModified
