Spring Boot Application:- The import org.springframework.boot.SpringApplication cannot be resolved - maven

Question

I'm beginner for Spring-boot;refering some tutorials I have set up a spring boot project using the Spring Initializer. I have tried to get rid of this issue by downloading dependencies again and even created new projects several times.
I'm using Eclipse neon IDE and I find error on imports import org.springframework.boot.SpringApplication.
I have removed repositories too many times so that jars will auto downloaded by itself when I refresh\clean the project but problem still persists.
DemoApplication.java
package com.example.demo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
#SpringBootApplication
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}
below is my pom.xml

Answer 1

Try doing this, I think this would solve
public static void main(final String[] aArgs)
{
new SpringApplicationBuilder(DemoApplication.class).run(aArgs);
}

Answer 2

within Eclipse: Right click Project -> Maven -> Update project should work

Answer 3

It was eclipse issue I found corrupted jars in repository and upgraded m2e to 1.8(solution found in Eclipse forum). After upgrading m2e I had removed my repository and restarted eclipse. Everything worked smooth 🙂
