【问题描述】：

我想使用电报 API，我在电报中创建 Bot 并设置用户名并获取令牌但我无法连接我的 java 代码请帮助我我用这个代码

ApiContextInitializer.init();
TelegramBotsApi telegramBotsApi = new TelegramBotsApi();
try {
    telegramBotsApi.registerBot(new TradeBot());
} catch (TelegramApiException e) {
    e.printStackTrace();
}

我的代理已设置，测试连接正确

public class TradeBot extends TelegramLongPollingBot {

    public void onUpdateReceived(Update update) {

    }

    public String getBotUsername() {
        return "xxx";
    }

    public String getBotToken() {
        return "xxx";

    }
}

在运行代码后给出这个错误：

在这里得到了回答：

Google Guice can't find class

您需要与您已经在使用的com.google.inject/guice 库相关的com.google.guava/guava 依赖项的正确版本。
