How can I override the jetbrains jdk dependency required by idea-ultimate or idea-community in config.nix? - intellij-idea

Question

I’ve been setting up my local nix config as per nixpkgs manual's declarative package management.
I’d like to include idea-ultimate as one of myPackages, but at this time the dependency idea has on the jetbrains jdk is broken, pointing to a non-existing package for macOS.
It’s trying to download jbrsdk-11_0_2-osx-x64-b485.1.tar.gz instead of jbrsdk-11_0_4-osx-x64-b485.1.tar.gz.
I was assuming I could fix that by overriding jetbrainsjdk as follows, but I’m getting: error: attribute 'jetbrainsjdk' missing, at /Users/ldeck/.config/nixpkgs/config.nix:4:20 when I do anything like nix-env -qa ‘jetbrains.*’.
What is the right way to override idea-ultimate so that it uses the fixed jdk?
Here’s my ~./config/nixpkgs/config.nix.
{
allowUnfree = true;
packageOverrides = pkgs: rec {
jetbrainsjdk = pkgs.jetbrainsjdk.override {
version = "520.11";
src = pkgs.fetchurl {
url = "https://bintray.com/jetbrains/intellij-jdk/download_file?file_path=jbrsdk-11_0_4-osx-x64-b${jetbrainsjdk.version}.tar.gz";
sha256 = "0d1qwbssc8ih62rlfxxxcn8i65cjgycdfy1dc1b902j46dqjkq9z";
};
};
myProfile = pkgs.writeText "my-profile" ''
export PATH=$HOME/.nix-profile/bin:/nix/var/nix/profiles/default/bin:/sbin:/bin:/usr/sbin:/usr/bin
export MANPATH=$HOME/.nix-profile/share/man:/nix/var/nix/profiles/default/share/man:/usr/share/man
'';
myPackages = with pkgs; buildEnv {
name = "my-packages";
paths = [
(runCommand "profile" {} ''
mkdir -p $out/etc/profile.d
cp ${myProfile} $out/etc/profile.d/my-profile.sh
'')

];
pathsToLink = [ "/share/man" "/share/doc" "/bin" "/etc" "/Applications" ];
extraOutputsToInstall = [ "man" "doc" ];
};
};
}
UPDATE 1
Thanks to #ChrisStryczynski who suggested I needed with pkgs, I’ve gotten a little further.
But now the problem is when attempting to install idea-ultimate with the custom jdk, it’s still requiring the broken, non-existing, jbrsdk-11_02-osx-x64-b485.1.tar.gz.drv from somewhere.
Updated config and logs below.

allowUnfree = true;

};
});
myIdeaUltimate = pkgs.jetbrains.idea-ultimate.override {
jdk = myJetbrainsJdk;

Answer 1

Thanks to How do you discover the override attributes for a derivation, a solution has been found using an overlay.
# ~/config/nixpkgs/overlays/02-jetbrains.nix
self: super:
{
jetbrains = super.jetbrains // {
jdk = super.jetbrains.jdk.overrideAttrs (oldAttrs: rec {
version = "520.11";
src = super.fetchurl {
url = "https://bintray.com/jetbrains/intellij-jbr/download_file?file_path=jbrsdk-11_0_4-osx-x64-b520.11.tar.gz";
sha256 = "3fe1297133440a9056602d78d7987f9215139165bd7747b3303022a6f5e23834";
};
passthru = oldAttrs.passthru // {
home = "${self.jetbrains.jdk}/Contents/Home";
};
});
idea-ultimate = super.jetbrains.idea-ultimate.overrideAttrs (_: {
name = "idea-ultimate.2019.2.4";
src = super.fetchurl {
url = "https://download.jetbrains.com/idea/ideaIU-2019.2.4-no-jbr.tar.gz";
sha256 = "09mz4dx3zbnqw0vh4iqr8sn2s8mvgr7zvn4k7kqivsiv8f79g90a";
};
});
};
}
Install: nix-env -iA 'nixpkgs.jetbrains.idea-ultimate'.
Execute: idea-ultimate.
The crucial part of the puzzle was overriding the passthru.home variable to point to the overlayed JDK rather than the one required by super. Otherwise, you’ll be downloading the old JDK for runtime purposes.
passthru = oldAttrs.passthru // {
home = "${self.jetbrains.jdk}/Contents/Home”;
};
Without /Contents/Home appended, idea won’t startup since self.jetbrains.jdk isn’t a valid home.

Answer 2

Instead of:
nix-env -iA nixpkgs.myPackages
Just do:
nix-env -iA nixpkgs.myIdeaUltimate
The problem being:
myPackages = with pkgs; buildEnv {
...
myIdeaUltimate
];
...
};
Here you are still referencing the old pkgs.myIdeaUltimate.
Nixos seems to do some processing that replaces the pkgs with the appropriate from packageOverrides.
