第二步：增加 patch3-SQOOP-COMPILE-FAST.diff 文件

在实际的 Sqoop 适配中，为进一步加快编译速度，推荐增加 patch3-SQOOP-COMPILE-FAST.diff 补丁。此 patch 主要优化了依赖管理逻辑和 Ivy 配置，让整体构建流程显著提速。

提示

如上图，补丁文件一般存放于 bigtop/package/src/sqoop/patches/ 目录，命名清晰便于维护。 patch3-SQOOP-COMPILE-FAST.diff 的主要目的是精简 ivy.xml 依赖声明和优化 ivysettings.xml 仓库配置，减少外网请求、关闭 checksum 校验，有效提升离线/内网编译成功率。

核心 diff 内容解析

下面是本补丁的主要内容及改动亮点：

+        </chain>

依赖提速

• 关闭校验算法与远程拉取，加快本地仓库依赖解析速度
• 优化 resolver 顺序，避免网络波动导致的编译卡死或失败

---

实战操作步骤

1. 将补丁文件放入 patches 目录，与主 spec/gradle 文件统一管理。
2. 确保 RPM spec 或 build.gradle 增加 patch 步骤，自动应用每次构建流程。
3. 编译时关注依赖拉取与 patch 生效情况，如遇 jar 缺失优先检查本地仓库或 tarball 包。

注意

如果 patch 应用后仍遇到依赖异常或拉取超时，建议：

• 复查 patch 内容是否与环境实际需求一致
• 本地仓库提前准备所有 jar，确保离线编译链路无死角
