[BenediktBroich]

Flake installation fails.

Command (shown in Readme.md):

nix run github:tadfisher/gradle2nix -- --help

Error:

There's a PR open for this, #50. Maybe it will work if you run nix run github:Scoder12/gradle2nix, until that PR is merged?

I asked in #75 (comment), but is this an expected hash change? Bumping hashes blindly is an anti-pattern.
