SpringBootServletInitializer not working on tomcat server

I'm trying to run my Spring Boot application on a local Tomcat 8 server, but can't get it to run. It works fine in Eclipse and mvn spring-boot:run.

I added the SpringBootServletInitializer and changed the pom.xml as recommended. But it seems that it never runs.

Here is the main class:

@SpringBootApplication
public class SasuApplication extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(SasuApplication.class);
    }

    public static void main(String[] args) {
        SpringApplication.run(SasuApplication.class, args);
    }

}

And here is my pom.xml

What am I missing?
