Breaking the Oracle Terms of Service in the nicest possible way.

Until very recently, it was possible to get sun-java7-jdk packages directly from Ubuntu. Then Oracle changed their TOS.

Then someone made an installer, which was ok.. But I wanted a debian package format.

So, all you need to do is:

For Java 7 u80:

1. Download the jdk-7u80-linux-x64.tar.gz file

2. Drop that file in src/var/cache/oracle-jdk7-installer/jdk-7u80-linux-x64.tar.gz

3. Install vagrant, virtualbox (you may need to log out and log in because you added a user to the vboxusers group)

sudo apt-get update
sudo apt-get install vagrant

4. Setup JAVA_VERSION variable in the env.vars

PATH=/home/vagrant/bin:$PATH
JAVA_VERSION=7u80

5. (Оptional) Setup distro name in the Vagrantfile

    db.vm.box = "ubuntu/xenial64"

6. Run building oracle java package

vagrant up

7. Builded package package will appear in the current directory, for example

ls -1 *.deb
oracle-java7-installer_7u80-custom-xenial-r100_amd64.deb

The biggest reason for doing it this way rather than using http://www.webupd8.org/2012/06/how-to-install-oracle-java-7-in-debian.html is because this way gives you a fat .deb file containing java, so you can install it in places that might not have connectivity (or have slow connectivity).

Also, Oracle will probably cripple the webupd8 method at some point, probably by putting a captcha in front of the downloads page. Wouldn't surprise me. The advantage of doing it this way is you do it once, update the deb build environment. Build the deb, install it. Done.
