I am trying to create a Spring Boot project.
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/xsd/maven-4.0.0.xsd">

</project>
SpringBootExample.java:
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class SpringBootExample {
public static void main(String[] args) {
SpringApplication.run(SpringBootExample.class, args);
}
}
When trying to execute the above class as a Java application I get an error:

Try to add this:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<!--<scope>provided</scope>-->
</dependency>
Or if you already have it comment this ( in this case i was using intellij debug button configuration) This project to be exact (GitHub petClinicSpringBoot)
<!--<scope>provided</scope>-->
