Thanks! Why did that not happen to other packages in systemPackages? Because they install sth into /run/current-system?

Sadly this does not work. The Gradle JavaFX plugin can take the path to the JavaFX SDK, but that SDK contains JARs and shared objects, while javaPackages.openjfx21 (and 22) contains the raw class files in one directory and the shared object in a separate directory (not sure how the classes will later find them). The JavaFX plugin just says Could not find org.openjfx:javafx-base:..

Maybe I have to write a Nix derivation to make this work?

tad: I'm trying to get gradle2nix v2 to build a particular artifact. I'm getting a "could not resolve plugin artifact error".

Here's the relevant section of gradle.lock :

  "com.gorylenko.gradle-git-properties:com.gorylenko.gradle-git-properties.gradle.plugin:2.4.1": {
    "com.gorylenko.gradle-git-properties.gradle.plugin-2.4.1.pom": {
      "url": "https://plugins.gradle.org/m2/com/gorylenko/gradle-git-properties/com.gorylenko.gradle-git-properties.gradle.plugin/2.4.1/com.gorylenko.gradle-git-properties.gradle.plugin-2.4.1.pom",
      "hash": "sha256-UbS0JAaOgoHJ1TEN9zZUDvoJqmqy73nInzwx3DHTwDg="
    }
  },
  "com.gorylenko.gradle-git-properties:gradle-git-properties:2.4.1": {
    "gradle-git-properties-2.4.1.jar": {
      "url": "https://plugins.gradle.org/m2/com/gorylenko/gradle-git-properties/gradle-git-properties/2.4.1/gradle-git-properties-2.4.1.jar",
      "hash": "sha256-QdGrigLNf7jfjxVz78B7QindwukExaTrXIxDWyXkBMM="
    },
    "gradle-git-properties-2.4.1.module": {
      "url": "https://plugins.gradle.org/m2/com/gorylenko/gradle-git-properties/gradle-git-properties/2.4.1/gradle-git-properties-2.4.1.module",
      "hash": "sha256-z4h44JHHIc4pRNdJeenjiXIBk4F4H81ogvFWK6jUfmA="
    },
    "gradle-git-properties-2.4.1.pom": {
      "url": "https://plugins.gradle.org/m2/com/gorylenko/gradle-git-properties/gradle-git-properties/2.4.1/gradle-git-properties-2.4.1.pom",
      "hash": "sha256-6Dn25xPK/62nzGUte/dgN546IEFrRSn54KErxmfe86s="
    }
  },

Here is how I'm using buildGradlePackage

packages.codegen = gradle2nix.builders.${system}.buildGradlePackage {
      name = "datahub";
      buildJDK = pkgs.jdk17;
      lockFile = ../gradle.lock;
      src = pkgs.fetchFromGitHub {
        owner = "datahub-project";
        repo = "datahub";
        rev = "v0.13.3";
        sha256 = "sha256-YccXGYnmnY+rUJmCDsAaROnxfvPX/iJW3OnPUDx0g2I=";
      };
      gradleInstallFlags = [":metadata-events:mxe-schemas:build"];
    };

Got any ideas? I'm not super familiar with gradle but this plugin's name looks kinda weird.

Here's the build log:

Welcome to Gradle 8.8!

Here are the highlights of this release:
 - Running Gradle on Java 22
 - Configurable Gradle daemon JVM
 - Improved IDE performance for large projects

For more details see https://docs.gradle.org/8.8/release-notes.html

To honour the JVM settings for this build a single-use Daemon process will be forked. For more on this, please refer to https://docs.gradle.org/8.8/userguide/gradle_daemon.html#sec:disabling_the_daemon in the Gradle documentation.
Daemon will be stopped at the end of the build 
Configuration on demand is an incubating feature.

Deprecated Gradle features were used in this build, making it incompatible with Gradle 9.0.

You can use '--warning-mode all' to show the individual deprecation warnings and determine if they come from your own scripts or plugins.

The "plugin artifact" is a POM-only dependency that's named "$pluginId.gradle.plugin". If the author doesn't publish that, then you need to include the plugin in the Gradle classpath some other way, either in settings.gradle with `pluginManagement` or with the old `buildscript.classpath` block.

In reply to @taffisher:matrix.org
was that log from a Nix build? because that means it's not trying to search the offline repository

In reply to @trexd:matrix.org
Yes it's from a nix build.

In reply to @taffisher:matrix.org
Thanks, I'll take a look in a bit. I think the setup hook isn't being applied. If this is in a flake, can you make sure ../gradle.lock is added to the Git index (git add --intent-to-add gradle.lock)?

In reply to @trexd:matrix.org
Tried it with git add --intent-to-add gradle.lock same issue. I appreciate you looking into it. Datahub is a very weird beast of a repo.
