> We'd still need to preserve whatever permissions are present in the Jetty distribution.
in jetty distribution there is just one shell startup script and you can 
even run jetty without it using autostartable jar. Requirement to 
preserve permissions is overkill. at most you need just to chmod +x one 
script. In tomcat it would be similar.

> Maven plugins, Groovy, or jtar would be limited in this respect.
In jtar you are manipulating resulting tar file directly:
