Nix派生错误:unpacker生成多个目录

我有以下推导来使用nix-flake安装jdtls文件。

{
  stdenv,
  fetchurl,
  gnutar,
  ...
}: stdenv.mkDerivation {
  pname = "jdtls";
  version = "1.28.0";

  src = fetchurl {
    url = "https://www.eclipse.org/downloads/download.php?file=/jdtls/snapshots/jdt-language-server-1.28.0-202309211406.tar.gz";
    sha256 = "q9O44I8iLuNT/eD1IDVnoa1TQgzEIhl2YF40wD0y/sA=";
  };

  nativeBuildInputs = [ gnutar ];

  buildPhase = ''
    ls -l
    # mkdir -p $out/share
    # tar -xf $src -d $out/share
    # mv $out/share/bin $out
  '';
}

在tar.gz文件中,压缩文件的根目录中有多个目录,这导致 nix build 由于此错误而失败。

文件夹:

â¯ tar -tf /nix/store/1m9df2gmnak6rkmf71vfnk36g724p6zb-jdt-language-server-1.28.0-202309211406.tar.gz

错误

â¯ nix log /nix/store/8r6v9l4825pxl76w7vy5nlv5drn6livs-jdtls-1.28.0.drv

是否解决此错误?

Nix对您下载的tar进行一些自动检测,假设它包含一个目录。要跳过它,您可以添加 sourceRoot = "."; 对你的推导是这样的:

{
  stdenv,
  fetchurl,
  gnutar,
  ...
}: stdenv.mkDerivation {
  pname = "jdtls";
  version = "1.28.0";

  src = fetchurl {
    url = "https://www.eclipse.org/downloads/download.php?file=/jdtls/snapshots/jdt-language-server-1.28.0-202309211406.tar.gz";
    sha256 = "q9O44I8iLuNT/eD1IDVnoa1TQgzEIhl2YF40wD0y/sA=";
  };

  sourceRoot = ".";

  nativeBuildInputs = [ gnutar ];

  buildPhase = ''
    ls -l
    # mkdir -p $out/share
    # tar -xf $src -d $out/share
    # mv $out/share/bin $out
  '';
}

你可以看到 in the default unpackPhase 它是如何出错的。
