如何覆盖 config.nix 中的 idea-ultimate 或 idea-community 所需的 jetbrains jdk 依赖项？

Question

我一直在按照 nixpkgs 手册 declarative package management 设置我的本地 nix 配置。

我想将 idea-ultimate 作为 myPackages 之一，但此时 idea 对 jetbrains jdk 的依赖是 broken，指向非-现有的 macOS 软件包。

正在尝试下载 jbrsdk-11_0_2-osx-x64-b485.1.tar.gz 而不是 jbrsdk-11_0_4-osx-x64-b485.1.tar.gz。

我假设我可以通过如下覆盖 jetbrainsjdk 来解决这个问题，但我得到：error: attribute 'jetbrainsjdk' missing, at /Users/ldeck/.config/nixpkgs/config.nix:4:20 当我做任何类似 nix-env -qa ‘jetbrains.*’.

的事情时

重写 idea-ultimate 以使其使用固定 jdk 的正确方法是什么？

这是我的 ~./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
        '')
    aspell
    bc
    coreutils
    direnv
    emacs
    emscripten
    ffmpeg
    gdb
    git
    hello
    jq
    nixops
    nox
    scala
    silver-searcher
      ];
      pathsToLink = [ "/share/man" "/share/doc" "/bin" "/etc" "/Applications" ];
      extraOutputsToInstall = [ "man" "doc" ];
    };
  };
}

更新 1

感谢@ChrisStryczynski 建议我需要 with pkgs，我已经更进一步了。

但现在的问题是，当尝试使用自定义 jdk 安装 idea-ultimate 时，它仍然需要来自某处的损坏的、不存在的 jbrsdk-11_02-osx-x64-b485.1.tar.gz.drv。

下面更新了配置和日志。

{
  allowUnfree = true;
  packageOverrides = pkgs: **with pkgs;** rec {

    myJetbrainsJdk = **pkgs.jetbrains.jdk.overrideAttrs** (oldAttrs: rec {
      version = "520.11";
      src = pkgs.fetchurl {
        url = "https://bintray.com/jetbrains/intellij-jdk/download_file?file_path=jbrsdk-11_0_4-osx-x64-b520.11.tar.gz";
        sha256 = "0d1qwbssc8ih62rlfxxxcn8i65cjgycdfy1dc1b902j46dqjkq9z";
      };
    });

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

    ...

    myPackages = with pkgs; buildEnv {
    ...
    myIdeaUltimate
      ];
      ...
    };
  };
}

Answer 1

而不是：

nix-env -iA nixpkgs.myPackages

就这样：

nix-env -iA nixpkgs.myIdeaUltimate

问题是：

  myPackages = with pkgs; buildEnv {
    ...
    myIdeaUltimate
      ];
      ...
    };

这里你仍然引用旧的pkgs.myIdeaUltimate。

Nixos 似乎做了一些处理，将 pkgs 替换为 packageOverrides 中的适当内容。

Answer 2

感谢 How do you discover the override attributes for a derivation，已找到使用覆盖的解决方案。

# ~/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";
      };
    });
  };
}

安装：nix-env -iA 'nixpkgs.jetbrains.idea-ultimate'.

执行：idea-ultimate.

难题的关键部分是覆盖 passthru.home 变量以指向覆盖的 JDK 而不是 super 所需的变量。否则，您将下载旧的 JDK 用于运行时目的。

passthru = oldAttrs.passthru // {
  home = "${self.jetbrains.jdk}/Contents/Home”;
};

如果不附加 /Contents/Home，idea 将不会启动，因为 self.jetbrains.jdk 不是一个有效的家。
