Generating verilog file for rocket chip

Question

I am a beginner working with rocket chip generator for my project but I am not able to generate the verilog file for it and facing this error. I am using an apple M1 chip macOS. I started with cloning the repository, installing the rocket tools for Mac (https://github.com/riscv-software-src/homebrew-riscv), jdk 17.0.10, sbt 1.9.9, Mill 0.11.7 and tried to generate the verilog. Are there some other steps involved?
