remove gradle flag --console=plain

[milahu]

the option --console=plain makes gradle fail with

Multiple arguments were provided for command-line option

because gradleSetupHook already adds --console plain since 2024-07-12

see also gradle/gradle#30913

FIXME update nixpkgs in flake.lock
this error only happens when calling gradle2nix from non-flake nix

How is this fixed by that change? I'm still getting the problem when building XTDB 2.0 that I added a Nix Flake to.

I'm still getting the problem

sure you are using the v2 branch with dff8e5b?

[nhooey]

@milahu: Yes I'm using that branch. I patched gradle2nix to get it working: by adding code to the setup-hook.sh shell script to strip the command-line option and value from the parameters.

Removing "--console=plain" from nix/build-gradle-package.nix had no effect.

I couldn't find console or plain anywhere in the gradle2nix v2 source code, or the xtdb 2.0.x code, so I have no idea where that duplicated --console parameter is coming from...

[nhooey]

sure you are using the v2 branch with dff8e5b?

Although, in that commit you linked, the unwrapped parameter is now gone in the v2 branch.

Although that doesn't matter because that package is only being called with an empty attribute set:

buildGradlePackage = callPackage ./build-gradle-package.nix { };

[milahu]

you can try postUnpack = "set -x"; or postPatch = "set -x";
to find the sources of the duplicate --console parameters in gradleFlags

the unwrapped parameter is now gone in the v2 branch

there never was an unwrapped parameter

dff8e5b uses gradle.passthru.unwrapped from
nixpkgs/pkgs/development/tools/build-managers/gradle/default.nix

      let
        gradle = gradle-unwrapped.override args;
      in
      # ...
        passthru = {
          # ...
          unwrapped = gradle;

nit: your remove_option_and_value function
works on --console plain but fails on --console=plain

if [ "${array_ref[$i]}" = "$option_to_remove" ]; then

I'm still getting the problem when building XTDB 2.0

feel free to share your code if youre stuck

non-flake example use of gradle2nix in my nur-packages:
gradle2nix.nix and gumtree.nix

[nhooey]

you can try postUnpack = "set -x"; or postPatch = "set -x";

The Bash was just a fix to continue for now. I'll find out where the extra command-line options are coming from. Thanks for the tip!

Thanks again! I have the XTDB database project almost building, it seems that gradle2nix is missing some libraries that I added to the gradle.lock file manually, but gradle isn't finding the libraries during nix build. Is there a bug in gradle2nix?

This is the XTDB 2.0.x_nix branch that I'm working on.

To see my commits just compare it to the 2.0.x branch:

git log --stat -p 2.0.x..2.0.x_nix

I also had to install protobuf as a nativeBuildInput because the gradle plugin for it was downloading.

I put some comments in the flake.nix file to show what I'm doing to build.

[nhooey]

Never mind about my build failures for the xtdb repository.

I added an extra build value to the command-line of xtdb:v2's flake.nix file, which added a lot of extra tasks for the nix build part, so many libraries didn't get included in gradle.lock.

[milahu]

the 2.0.x branch seems outdated

This branch is 9 commits ahead of, 138 commits behind main

v2.0.0 is on the main branch

building xtdb is the easy part, see xtdb.nix
(sorry i didnt debug your flake.nix)

installing and running xtdb is the hard part...

most jar files dont works with java -jar $jar

$ java -jar ./result/opt/xtdb/http-server/build/libs/xtdb-http-server-2.0.0-SNAPSHOT.jar
no main manifest attribute, in ./result/opt/xtdb/http-server/build/libs/xtdb-http-server-2.0.0-SNAPSHOT.jar

the "standalone" jar file does not work

$ java -jar ./result/opt/xtdb/docker/standalone/build/libs/xtdb-standalone.jar
Clojure 1.12.0
user=> (dev)
Syntax error compiling at (REPL:1:1).

user=> (go)

im trying to replicate ./gradlew :clojureRepl

docs are not helpful

maybe you know more to get this running
expected: $out/bin/xtdb should run the database server

[nhooey]

How did you get the gradle2nix locking to include all of the libraries that are needed to build?
I'm having to insert a lot of files manually...

[nhooey]

The XTDB v2.0.0 Dockerfile has the parameters you need to get it running.

(I haven't confirmed that it actually works, I just found it.)

[milahu]

its still a mystery why this works with nix-build and breaks with nix flake

it seems like gradle.passthru.unwrapped is not passed to gradle2nix

debug: require gradle.passthru.unwrapped in gradle2nix/nix/gradle-setup-hook.nix

   gradle-unwrapped =
-    if gradle ? passthru && gradle.passthru ? unwrapped then gradle.passthru.unwrapped else gradle;
+    gradle.passthru.unwrapped;

in contrast, removing the --console=plain flag does work in 8f20348 and 40abf29

alternative: replace --console=plain with -Dorg.gradle.console=plain (#92)
