This adds JAVA_HOME to the global environment, by sourcing the
|
|
jdk's setup-hook on shell init. It is equivalent to starting a shell
|
|
through 'nix-shell -p jdk', or roughly the following system-wide
|
|
configuration:
|
|
|
|
environment.variables.JAVA_HOME = ''${pkgs.jdk.home}/lib/openjdk;

environment.systemPackages = [ pkgs.jdk ];
