Попытка запустить сервер Springboot, используя Spark, но получает некоторые ошибки при запуске ⇐ JAVA

[Anonymous]

У меня есть следующие 2 класса, которые используют пакет Spark, и которые запускают сервер через Springboot. < /p>
package server;

import static spark.Spark.get;
import static spark.Spark.port;
import static spark.Spark.post;

import phone.PhoneSystem;

public class Server
{
public static void run()
{
port(4567);

try(PhoneSystem phone = new PhoneSystem())
{
get("/voice", (request, response) ->
{
return phone.startupMessage(request, response);
});

post("/process", (request, response) ->
{
return phone.messageLoop(request, response);
});
}
}
}
< /code>
package server;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class MyApplication
{
public static void main(String[] args)
{
SpringApplication.run(MyApplication.class, args);
Server.run();
}
}
< /code>
I am trying to run the server using the following command:
mvn exec:java -Dexec.mainClass="server.MyApplication"
< /code>
But it is giving me the following error output:
java.lang.NoClassDefFoundError: spark/embeddedserver/jetty/JettyHandler

I tried switching to Spark 3.0.0 in order to fix this problem but it seems that this version of Spark is not available on Maven Central. I also tried removing the Jetty dependencies and tried to use snapshot versions within a repository in the pom.xml file but I still get the same error messages.
For reference I am using the following dependencies in my pom.xml file:

com.sparkjava
spark-core
2.9.4



org.eclipse.jetty
jetty-server



org.eclipse.jetty
jetty-servlet
9.4.44.v20210927
