Lights, Camera, GitHub Actions!
summary
Covers how to use GitHub Actions end to end: YAML workflows with matrix across four runners (Linux, macOS Intel/ARM, Windows), Maven caching, secrets, job outputs and dependencies, and reusable workflows to remove duplication. Shows a composite Java action that downloads a JAR and runs JReleaser, builds GraalVM native images for four platforms, uploads artifacts, and creates a GitHub release — the pipelines run successfully and Sysmore audits ~109 configuration issues for remediation.
