I am currently learning how to use apache-storm and apache-kafka. I've tried to solve the problem by looking for other dependencies to add in the pom, but all the solutions that I found were related to apache-spark-streaming. You can find below the code and the pom.

the code:

package analytics;

import java.util.Properties;

import org.apache.storm.Config;
import org.apache.storm.LocalCluster;
import org.apache.storm.StormSubmitter;
import org.apache.storm.generated.AlreadyAliveException;
import org.apache.storm.generated.AuthorizationException;
import org.apache.storm.generated.InvalidTopologyException;
import org.apache.storm.generated.StormTopology;
import org.apache.storm.kafka.spout.KafkaSpout;
import org.apache.storm.kafka.spout.KafkaSpoutConfig;
import org.apache.storm.topology.TopologyBuilder;
import org.apache.storm.topology.base.BaseWindowedBolt;
import org.apache.storm.tuple.Fields;
import org.apache.kafka.clients.consumer.ConsumerConfig;

public class App 
{
    public static void main( String[] args )throws Exception, AlreadyAliveException, InvalidTopologyException, AuthorizationException
    {
        TopologyBuilder builder = new TopologyBuilder();
        
        KafkaSpoutConfig.Builder<String, String> spoutConfigBuilder = KafkaSpoutConfig.builder("localhost:9092", "velib-stations");
        Properties prop = new Properties();
        prop.setProperty(ConsumerConfig.GROUP_ID_CONFIG, "city-stats");
        spoutConfigBuilder.setProp(prop);
        KafkaSpoutConfig<String, String> spoutConfig = spoutConfigBuilder.build();
        builder.setSpout("stations", new KafkaSpout<String, String>(spoutConfig));
        
        builder.setBolt("station-parsing", new StationParsingBolt())
            .shuffleGrouping("stations");
        
        builder.setBolt("city-stats", new CityStatsBolt().withTumblingWindow(BaseWindowedBolt.Duration.of(1000*60*5)))
            .fieldsGrouping("station-parsing", new Fields("city"));
        
        builder.setBolt("save-results",  new SaveResultsBolt())
            .fieldsGrouping("city-stats", new Fields("city"));
        
        StormTopology topology = builder.createTopology();

        Config config = new Config();
        config.setMessageTimeoutSecs(60*30);
        String topologyName = "velos";
        if(args.length > 0 && args[0].equals("remote")) {
            StormSubmitter.submitTopology(topologyName, config, topology);
        }
        else {
            LocalCluster cluster = new LocalCluster();
            cluster.submitTopology(topologyName, config, topology);
        }
    }
}
