+JNI 头文件生成系统
+${'=' * 70}
+
+📋 概述:
+   为包含 native 方法的 Java 类生成 C/C++ 头文件。
+
+🚀 快速开始:
+   1. ./gradlew createJniConfig          # 创建配置文件
+   2. 编辑 config/jni-classes.txt        # 添加你的 JNI 类
+   3. ./gradlew generateJniHeaders       # 生成头文件（推荐）
+   4. 头文件输出到: cpp/header/
+
+🔧 可用任务:
+   jniHelp                  - 显示此帮助
+   createJniConfig          - 创建配置文件
+   generateJniHeaders       - 生成头文件（现代方式）
+   generateJniHeadersLegacy - 传统方式（Java 8-9）
+   scanForNativeMethods     - 扫描 native 方法
+   verifyJniSetup           - 验证配置
+   cleanJniHeaders          - 清理生成的文件
+
+📝 配置文件格式 (config/jni-classes.txt):
+   # 注释
+   com.example.MyNativeClass     # 直接指定类名
+   #auto:.*Native.*              # 自动匹配（以 #auto: 开头）
+
+⚠️  注意事项:
+   • 确保类中包含 native 方法声明
+   • 先编译项目再生成头文件
+   • 对于 Java 10+ 使用 generateJniHeaders
+   • 对于 Java 8-9 使用 generateJniHeadersLegacy
+
+🔍 调试:
+   • 运行 verifyJniSetup 检查环境
+   • 运行 scanForNativeMethods 发现 native 类
+   • 确保源文件中有 native 关键字
