第二步：补丁文件必须命名为 patch0-DATASOURCE-OPTIMIZED.diff 并放到指定目录

在执行依赖适配之前，请先将补丁文件命名为 patch0-DATASOURCE-OPTIMIZED.diff ，并放到 bigtop-packages/src/common/dolphinscheduler/ 目录下。这一步是自动 patch 流程能否生效的关键，切勿遗漏或随意更名！

如上图所示

• 文件名必须为 patch0-DATASOURCE-OPTIMIZED.diff，**
• 路径为 bigtop-packages/src/common/dolphinscheduler/
• 不要随意更名，不要放错目录，否则自动 patch 步骤会直接失效。**
