- Pin to eclipse-temurin:21.0.10_7-{jdk,jre}-noble for reproducible builds
- Switch -DskipTests to -Dmaven.test.skip=true: skips test compilation entirely,
not just execution — faster and avoids build failures from test-only missing classes
- Add comment on COPY *.jar explaining why the glob is safe (Spring Boot renames
the pre-repackage artifact to .jar.original, leaving only one .jar in target/)
