Как выглядят классы: ` public class MyBot extends LongPollBot {

@Override
public void onMessageNew(MessageNewEvent messageNewEvent) {
    Message message = messageNewEvent.getMessage();
    if (message.hasText()) {
        String response = "Hello! Received your message: " + message.getText();
        try {
            new MessagesSend(this)
                    .setPeerId(message.getPeerId())
                    .setMessage(response)
                    .execute();
        } catch (BotsLongPollHttpException e) {
            e.printStackTrace();
        } catch (BotsLongPollException e) {
            e.printStackTrace();
        }
    }
}

@Override
public String getAccessToken() {
    return "токен";
}

@Override
public int getGroupId() {
    return ид;
}

} `

` public class Application {

public static void main(String[] args) throws ClientException, ApiException, IOException, BotsLongPollHttpException, BotsLongPollException {
    new BotsLongPoll(new MyBot()).run();
}

} `

Можете поделится примером JSON, который вы получаете?

Чтоб получить JSON нужно:

1. Добавить в pom.xml:

   <dependency>
   <groupId>org.slf4j</groupId>
   <artifactId>slf4j-simple</artifactId>
   <version>1.7.30</version>
   </dependency>

2. Установить уровень логирования DEBUG в методе main:

   public static void main(String[] args) {
   System.setProperty(SimpleLogger.DEFAULT_LOG_LEVEL_KEY, "DEBUG");
   new BotsLongPoll(new MyBot()).run();
   }

   Этот JSON должен содержать поле "type": "message_new" Пример такого JSON: https://github.com/yvasyliev/java-vk-bots-long-poll-api/blob/master/src/test/resource/json/response/message_new/message_new_photo_sample_5_110.json

Теперь к началу предыдущей ошибки добавилось это: SLF4J: Class path contains multiple SLF4J bindings. SLF4J: Found binding in [jar:file:/C:/Users/aleha/.m2/repository/org/apache/logging/log4j/log4j-slf4j-impl/2.11.2/log4j-slf4j-impl-2.11.2.jar!/org/slf4j/impl/StaticLoggerBinder.class] SLF4J: Found binding in [jar:file:/C:/Users/aleha/.m2/repository/org/slf4j/slf4j-simple/1.7.30/slf4j-simple-1.7.30.jar!/org/slf4j/impl/StaticLoggerBinder.class] SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation. SLF4J: Actual binding is of type [org.apache.logging.slf4j.Log4jLoggerFactory] ERROR StatusLogger No Log4j 2 configuration file found. Using default configuration (logging only errors to the console), or user programmatically provided configurations. Set system property 'log4j2.debug' to show Log4j 2 internal initialization logging. See https://logging.apache.org/log4j/2.x/manual/configuration.html for instructions on how to configure Log4j 2

[yvasyliev]

Похоже, что у вас в проекте уже подключена log4j 2 имплементация.

В таком случае:

1. Уберите

   <dependency>
   <groupId>org.slf4j</groupId>
   <artifactId>slf4j-simple</artifactId>
   <version>1.7.30</version>
   </dependency>

2. Поместите в папку resource файл log4j2.xml:

   <?xml version="1.0" encoding="UTF-8"?>
   <Configuration status="WARN">
   <Appenders>
       <Console name="Console" target="SYSTEM_OUT">
           <PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n"/>
       </Console>
   </Appenders>
   <Loggers>
       <Root level="debug">
           <AppenderRef ref="Console"/>
       </Root>
   </Loggers>
   </Configuration>

3. Запустите приложение:

   public static void main(String[] args) {
   new BotsLongPoll(new MyBot()).run();
   }
