gradle2nix fails on android project: conversations

[DavHau]

We are currently trying to package https://github.com/iNPUTmice/Conversations

We have difficulties using gradle2nix.
It would be great to get some help.

reproduce:

nix-shell -p nixFlakes
git clone --branch gradle2nix-app https://github.com/DavHau/conversations
cd conversations/sphinx-style
nix run .#run-gradle2nix

The code of the flake app can be found in sphinx-approach/flake.nix

Seems like the wrong jdk was used. Now the gradle2nix tool runs successfully, but the build fails, complaining about all dependencies from gradle-env.json missing. So something must still go wrong with what gradle2nix does, it seems.
I updated the branch from above.
