how to build and run an IDE Maven project

Question

Good afternoon,

I’m trying to generate an application for studies using Maven, but this disastrous and very frustrating.

I’m trying to create a web project using Maven, but I can’t do anything to make it run, however I’m trying to do everything for IDE, ta tried several web Servers and web containers, but none of them actually goes up the application.

I tried to configure the wildfly in a traditional way, so the project goes up normally, but when converting msm to Maven it stops running, the same happens if I create the project as a project Maven webapp.

I tried to add the wildfly plugin and later Jetty and in none of the cases I succeeded, when trying "Maven>update project" it does not even download the server, consequently it does not run it, the same happens with Jetty and it is clear if it keeps the error:

Description Resource Path Location Type The superclass "javax.servlet.http.Httpservlet" was not found on the Java Build Path

clearly due to lack of a web server or container Servlet

follow my pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <groupId>br.com.lsoft</groupId>
  <artifactId>gameapi</artifactId>
  <packaging>war</packaging>
  <version>0.0.1-SNAPSHOT</version>
  <name>gameapi Maven Webapp</name>
  <url>http://maven.apache.org</url>

  <dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>3.8.1</version>
      <scope>test</scope>
    </dependency>
  </dependencies> 

  <build>
    <finalName>gameapi</finalName>

    <plugins>
        <plugin>
            <groupId>org.wildfly.plugins</groupId>
            <artifactId>wildfly-maven-plugin</artifactId>
            <version>13.0.0.Final</version>
            <configuration>
                <port>8081</port>
            </configuration>
        </plugin>
    </plugins>

  </build>
</project>

That leaves me with a few simple questions:

whenever I go to work with Maven I am obliged to use cmd to compile and run the project? if it is not, because this was not demonstrated in the class in question, in this case it is already the suggestion to redo this class, or create one more for this course, teaching how to do it.

when analyzing the created "web.xml" I realized that the project was created with the default Servlet 2.3, how do I make the project to be created with a later version?? follows the web.xml

<!DOCTYPE web-app PUBLIC
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app>
  <display-name>Archetype Created Web Application</display-name>
</web-app>

Good night.

I think the simplest option is to create the project through the Spring Boot start site, in case you mentioned using only MAVEN, https://start.spring.io/ after you download and import a Maven project by selecting the unzipped directory.
