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

setSignedjar

public void setSignedjar(java.io.File signedjar)

name of signed JAR file; optional

Parameters:

setInternalsf

public void setInternalsf(boolean internalsf)

Flag to include the .SF file inside the signature; optional; default false

Parameters:

Optionally sets the output directory to be used.

Parameters:

getMapper

public FileNameMapper getMapper()

get the active mapper; may be null

Returns:

mapper or null

Since:

Ant 1.7

getTsaurl

public java.lang.String getTsaurl()

get the -tsaurl url

execute

public void execute()
             throws BuildException

sign the jar(s)

isUpToDate

protected boolean isUpToDate(java.io.File jarFile,
                             java.io.File signedjarFile)

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 Essentially if either file doesnt exist, or the destfile has an out of date timestamp, then the return value is false.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.

Parameters:

file - the file to be checked

Returns:

true if the file is signed

See Also:

IsSigned.isSigned(File, String)

setPreserveLastModified

public void setPreserveLastModified(boolean preserveLastModified)

true to indicate that the signed jar modification date remains the same as the original. Defaults to false

Parameters:

preserveLastModified - if true preserve the last modified time
