I've updated my Gradle 9.1.0 (draft) PR to 9.1.0-rc-3: https://github.com/NixOS/nixpkgs/pull/434086

And via my nixpkgs-jdk-ea fork (where I have merged master with Gradle 9.1 rc 3 on the jdk-ea-25 branch) I've built a handful of projects with GraalVM 25 and everything seems to be working quite nicely.

I expect there to be final Gradle 9.1.0 pretty soon and I'll update the PR and request review at that time. If anyone wants to kick the tires that would be great.

I updated this Zulu 25 PR: https://github.com/NixOS/nixpkgs/pull/421377 now that they finally made packages available for the 4 main platforms (no JFX yet, though)

It's getting that nixpkgs-vet CI failure about "Attribute pkgs.zulu25 is a new top-level package using `pkgs.callPackage" and I'm not sure what to do about that.

Yeah, I think the existing code can be made simpler and optionally support EA releases. But we're running out of time for 25-EA releases because G.A. is happening on Tuesday 9/16.

nix-jabba looks like it covers the use-cases that I currently use SDKMAN! for -- that's cool!

But, I still think having EA releases in Nixpkgs will be helpful for working on flakes (inside and outside of Nixpkgs) that have dependencies on EA JDKs and possibly other packages (such as Gradle) That's why I made the nixpkgs-jdk-ea repo (which might be better implemented as an overlay)

The Zulu PR is failing nixpkgs-vet with the following message:

Attribute `pkgs.zulu25` is a new top-level package using `pkgs.callPackage ./pkgs/development/compilers/zulu/25.nix { /* ... */ }`.
  Please define it in pkgs/by-name/zu/zulu25/package.nix instead.
  See `pkgs/by-name/README.md` for more details.
  Since the second `callPackage` argument is `{ }`, no manual `callPackage` in pkgs/top-level/all-packages.nix is needed anymore.

This PR introduces additional instances of discouraged patterns as listed above. Merging is discouraged but would not break the base branch.
