mvn2nix lock file missing a dependency

Trying to port circuitjs1 to nix is not working. The build process reports a missing dependency:

> nix run
error: builder for '/nix/store/jj93snq27rw8yjbn0sp6id40nwx127xv-circuitjs1-0.9.3.drv' failed with exit code 1;

The relevant repository can be found here, complete with a Nix flake that should work fine if you want to reproduce the error: https://github.com/crabdancing/circuitjs1

Any help would be greatly appreciated :)
