- Dockerfile.deps/template: 改用阿里云镜像手动安装 Maven，避免 apk maven 拉入冗余 openjdk25（600MB+）导致构建超时 - Jenkinsfile: 添加 DOCKER_BUILDKIT=1，使层缓存真正生效 - Dockerfile.deps: framework/dependencies 源码在 COPY . . 前单独复制并预编译， 提升缓存命中率；mvn install 去掉 || true，编译失败立即报错 - .dockerignore: 补充 .git/、docs/、sql/、scripts/ 等目录，构建上下文从 60MB 降至 ~5MB Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
