> Once {{JarFinder.getJar()}} is invoked by a client app, it would be really useful to
destroy the generated JAR after the JVM is destroyed by setting {{tempJar.deleteOnExit()}}.
In order to preserve backwards compatibility a configuration setting could be implemented,
e.g. {{test.build.dir.purge.on.exit}}
