What ide are you using? If you set a property at the start of the build
script that sets java.home to your SDK, then it should use that. I know in
NetBeans that properties are immutable, so once set they will not be set
again. I am not sure about other environments, but I would guess this is a
feature of ANT and not the IDE.
