| name: "Copilot Setup Steps" | |
| # Prepares the GitHub Copilot coding agent's ephemeral environment so it can | |
| # build this extension and reproduce bugs with AutoTest UI/E2E plans without a | |
| # slow trial-and-error dependency hunt. | |
| # | |
| # The `copilot-setup-steps` job runs BEFORE Copilot starts working. It mirrors | |
| # the Linux path of `.github/workflows/e2eUI.yml`: JDK 21 + Node 20, the OSGi | |
| # bundle build (which also warms the Maven cache), the AutoTest CLI, and the | |
| # Xvfb / GTK libraries required to launch VS Code headless. | |
| # | |
| # NOTE: This workflow only takes effect once it is on the default branch. | |
| # | |
| # Setup steps run BEFORE the Copilot agent firewall is enabled, so the final | |
| # step pre-downloads VS Code (stable) and the Java Extension Pack into AutoTest's | |
| # `<repo>/.vscode-test` cache. That warms the exact files AutoTest fetches from | |
| # the VS Code CDN + Marketplace at run time — hosts the firewall blocks — so the | |
| # firewalled UI reproduction launches offline. See .github/skills/repro/SKILL.md. | |
