I doubt that the jenkins managed gradle plugin will penetrate far enough
into the debbuild process as it's running inside a chroot.

I expect that adding a rule to the debian/rules file might be the "correct"
solution.  Something like override_dh_auto_install which probably is doing
something like "sudo make install" as the last step of a CMake based build
system.  I haven't found out exactly what it does, but that might fix it.
