The build system adds these inputs by default:

         (build-inputs `(("jdk" ,jdk "jdk")
                         ("ant" ,ant)
                         ("zip" ,zip)
                         ,@native-inputs))

You should be able to override each of these by specifying them as a
keyword argument, e.g.

    (arguments
     `(#:jdk ,some-other-jdk
       #:zip ,some-other-zip))

Ouch!  This shouldn’t have been committed.  This is what happened pretty
often with my terrible keyboard at work — my control key (among many
other keys) wasn’t very reliable and would sometimes stop working while
I moved around in the sources in Emacs (where Ctrl+p moves up one
line).

I’m surprised this doesn’t lead to an error.
