多语言编码Agent解决方案（4）-Eclipse插件实现

Eclipse插件实现：支持多语言的编码Agent集成

本部分包含Eclipse插件的完整实现，包括多语言支持、命令注册、API调用和UI集成。插件使用Java开发，基于Eclipse Plugin Development Environment (PDE)。

1. Eclipse插件目录结构

eclipse-plugin/
├── src/                           # 源代码
│   └── com
│       └── codingagent
│           ├── Activator.java     # 插件激活器
│           ├── AgentCommands.java # 命令处理类

2. 国际化支持 (Messages.java)

// src/com/codingagent/i18n/Messages.java
package com.codingagent.i18n;import java.util.ResourceBundle;
import java.util.Locale;public class Messages {private static ResourceBundle bundle;static {// 获取当前LocaleLocale locale = Locale.getDefault();String lang = locale.getLanguage();// 选择语言文件if (lang.equals("zh")) {bundle = ResourceBundle.getBundle("locales.messages", Locale.SIMPLIFIED_CHINESE);} else if (lang.equals("ja")) {bundle = ResourceBundle.getBundle("locales.messages", Locale.JAPANESE);} else {bundle = ResourceBundle.getBundle("locales.messages", Locale.ENGLISH);}}public static String getString(String key) {try {return bundle.getString(key);} catch (Exception e) {return key; // 回退到key}}public static String getString(String key, Object... params) {String message = getString(key);if (params != null) {for (int i = 0; i < params.length; i++) {message = message.replace("{" + i + "}", params[i].toString());}}return message;}
}

3. 语言文件 (locales)

</plugin>

8. 清单文件 (META-INF/MANIFEST.MF)

Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Name: Coding Agent Eclipse Plugin
Bundle-SymbolicName: com.codingagent;singleton:=true
Bundle-Version: 1.0.0.qualifier
Bundle-Activator: com.codingagent.Activator
Require-Bundle: org.eclipse.ui,org.eclipse.core.runtime,org.eclipse.jface.text,org.eclipse.ui.editors
Bundle-RequiredExecutionEnvironment: JavaSE-11

9. 构建属性 (build.properties)

source.. = src/
output.. = bin/
bin.includes = META-INF/,\.,\plugin.xml,\resources/

这个Eclipse插件实现提供了完整的编码辅助功能，支持多语言界面，并与本地后端服务集成。注意：实际开发中可能需要添加更多依赖和错误处理。
