shell.nix

#
# The Nix configuration allows to start up a shell with complete project environment (required tools).
# The environment allows for building and contribution to the repository.
#
# The environment is local- does not mess with the global configuration of your PC.
#
# 1. To start you need to install Nix first: https://nixos.org/guides/install-nix.html
# 2. Next step is to start up the project environment with a command:
#        nix-shell
#
# Project environment consists of:
#  - JDK8 package that is used by Liferay
#  - maven
#  - git
#  - bash shell with command completion
