Install and setup the Java development kit.
::: {.note}
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 ];
:::
'';
};
package = mkOption {
default = pkgs.jdk;
defaultText = literalExpression "pkgs.jdk";
description = lib.mdDoc ''
Java package to install. Typical values are pkgs.jdk or pkgs.jre.
