Summary of Changes

Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request updates the SCIO Docker configuration to ensure a more reliable and secure build environment. By migrating to a modern GPG-based key management system for the SBT repository and pinning the SBT version, the build process becomes more deterministic and resilient to upstream changes.

Highlights

• SBT Installation Update: Updated the SBT installation process in the Dockerfile to use a more secure, modern approach with GPG keyrings and pinned the version to 1.10.11.
• Docker Image Optimization: Improved cleanup of apt lists and removed unnecessary temporary files to keep the image size lean.

Code Review

This pull request updates the sbt installation process in the scio backend Dockerfile to use modern GPG keyring practices instead of the deprecated apt-key utility, pins the sbt version to 1.10.11, and cleans up package lists. Feedback suggests downloading the GPG key to a temporary file instead of piping curl directly to gpg --dearmor to prevent silent pipeline failures.

Important

The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.
For more details on the timeline and next steps, please review the Help Documentation.

Using a pipe (|) with curl can lead to silent failures because the default shell (/bin/sh) does not have pipefail enabled by default. If the curl command fails (e.g., due to network issues or keyserver downtime), the pipeline might still exit with a success status, leading to an empty or corrupted keyring file and causing harder-to-debug failures later in the build process.

To prevent this, download the key to a temporary file first, dearmor it, and then remove the temporary file.

    && gpg --dearmor -o /etc/apt/keyrings/scalasbt.gpg /tmp/scalasbt.key \
    && rm /tmp/scalasbt.key \
