spring boot - Cannot Resolve Symbol @SpringBootApplication - IntelliJ DEA

Question

I imported a Spring Initializr build to IntelliJ and then run it as a Spring Boot build. The build works fine and displays in the browser but I continue to receive an error about unused imports and that @SpringBootApplication cannot be resolved. I also followed these steps as well: Cannot resolve symbol SpringApplication

Anyone else has this issue.

package com.sts.kevthedev;

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

@SpringBootApplication
public class KevthedevApplication {

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

Try it:
