With v3 you only need to run install.sh once, so that needs to be done
from the installation (unpacked distribution) directory.

> But below, under "Rebuilding the war file" it says, "If you need to

That probably should be %{idp.home} instead of 'the installation directory'.
Can't hurt to make that change?
