FireSim Version and Hash

1.17.1-128-g06bc1c243

OS Setup

<!-- copy/paste the output of `uname -a; lsb_release -a` below -->

Linux roquefort 5.15.0-86-generic #96-Ubuntu SMP Wed Sep 20 08:23:49 UTC 2023 x86_64 GNU/Linux
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 22.04.3 LTS
Release: 22.04
Codename: jammy

Other Setup

Fresh Chipyard clone, which clones FireSim: f42435985182f1f3a484605ba9ae7a287c0a9b10.
Then manually fetch & checkout upstream main branch, which is AFTER: 2f13158e0ee8f5880db993d1a50e1d87c32ebe31 (Initial support for Fat JARs).

Custom Chipyard environment which branches from commit 4a1189693d8134973010ac91abf7f085bbf0b49d and has only minor alterations.
Development environment with Nix:
Nix:
nix (Nix) 2.18.0

Java, Scala, SBT versions:
Java: 17.0.7 & 19.0.2
Scala: 2.13.10
SBT: 1.7.3, 1.8.3, 1.9.2

Current Behavior

Running any SBT command in Chipyard (which is older, but does not seem related) causes SBT to stop and ask for user input on whether to load the project or not.

Expected Behavior

Any SBT command should load the project correctly, even if FireSim is not used for simulation acceleration.
