+## Maintaining the Java Module Descriptor
+
+Fesod ships an optional Java Platform Module System (JPMS) descriptor that is compiled when the build runs on JDK 9 or newer. When you add a new public package or rely on additional reflective access, remember to:
+
+- Update `fesod/src/main/java9/module-info.java` and export any new public packages that should be reachable by module consumers.
+- Extend the Java 9+ Surefire arguments (`surefire.jdk9plus.args` property in `fesod/pom.xml`) if new reflective code requires `--add-opens` access to JDK or third-party modules.
+- Run `ModuleDefinitionTest` to confirm the module stays open and reflective access continues to work. Maven will execute it automatically via `./mvnw test -pl fesod` on JDK 11+.
+- Keep Java 8 compatibility: all new code must still compile with the Java 8 toolchain even after updating the module descriptor.

+## 模块化维护注意事项
+
+Fesod 在 JDK 9 及以上版本会额外编译 JPMS 模块描述文件。新增对外公开的包或依赖新的反射访问时,请同步完成以下调整:
+
+- 修改 `fesod/src/main/java9/module-info.java`,为需要暴露给使用方的包添加新的 `exports`。
+- 如果新增代码需要访问 JDK 或三方模块的内部类型,请在 `fesod/pom.xml` 的 `surefire.jdk9plus.args` 中补充相应的 `--add-opens`。
+- 运行或关注 `ModuleDefinitionTest`,确保模块保持 `open` 状态且反射能力未被破坏;在 JDK 11+ 环境执行 `./mvnw test -pl fesod` 时会自动覆盖该测试。
+- 继续保持 Java 8 兼容性:即使更新了模块描述符,新代码仍需通过 Java 8 编译器编译。
