Java#

The Java role installs installs OpenJDK 8.

Note that on the NixOS platform it is not strictly necessary to activate a role to install software. You can install Java into the service-user:

ssh your-vm
sudo -iu s-youserservice
nix-env -iA nixos.jdk

To find out about which java packages are available, see the NixOS packages index. We also have some guidance for automatically installing Oracle Java.
