+# 01-技术选型
+
+## 推荐技术栈
+
+### 1. UI框架
+**选择：JavaFX**
+
+**理由：**
+- 现代化UI组件，支持CSS样式定制
+- 响应式布局，适合构建复杂的SVN管理界面
+- 官方Scene Builder可视化设计工具，开发效率高
+- 跨平台性好
+
+**对比Swing：**
+- Swing虽然成熟，但UI组件较为陈旧
+- JavaFX提供更丰富的动画和视觉效果
+- JavaFX更适合现代桌面应用开发
+
+### 2. 构建工具
+**选择：Maven**
+
+**理由：**
+- 生态成熟，依赖管理简单
+- 项目结构标准化
+- 插件丰富
+- 社区支持好
+
+### 3. 进程执行
+**选择：ProcessBuilder**
+
+**理由：**
+- Java原生，无需额外依赖
+- 足够应对SVN命令调用需求
+- 支持环境变量配置和工作目录设置
+
+**可选增强：**
+- Apache Commons Exec（提供更高级的进程管理功能）
+
+### 4. Java版本
+**选择：Java 11+**
+
+**理由：**
+- LTS（长期支持）版本，稳定可靠
+- JavaFX支持良好
+- 性能优化完善
+
+### 5. 辅助库（可选）
+- **Jackson/Gson**: JSON解析，解析SVN的XML/JSON输出格式
+- **Logback/SLF4J**: 日志管理
+- **JUnit 5**: 单元测试
+
+## 架构设计
+
+### MVC模式

+## 核心功能模块
+
+### 1. 仓库管理
+- Checkout检出仓库
+- Update更新仓库
+- Commit提交修改
+
+### 2. 文件操作
+- Add添加文件
+- Delete删除文件
+- Revert回退文件
+
+### 3. 版本查看
+- Status查看状态
+- Log查看日志
