Answer 1

An alternative would be to base your build on a maven script.
Maven does propose the jarsigner:verify plugin

If that is not a valid possibility, you still can use the Exec ant task to directly call the jarsigner command.
If the return code is correctly set, you can add the attribute failonerror (Stop the buildprocess if the command exits with a returncode other than 0.)
