package org.springframework.boot does not exist

I am trying to run a Small basic Spring boot program on my machine and I when I run clean compile (even before trying spring-boot:run) on maven I get the following Error :

And here is my java Class :

package com.benayed.spboot.poc.SpringBootPoc;

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

@SpringBootApplication
public class SpringBootPocApplication {

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

}

I tried many solutions I could find on internet, such as deleting the .m2 repository, adding different tags (version, fork,...) to the spring-boot-maven-plugin plugin which, I'm pretty sure, is the part causing the problem

Any suggestions ?

How to fix java package org springframework boot does not exist?

To Solve package org. springframework. boot does not exist Error You just need to check your Pom. xml and make sure your spring-boot-starter-data-jpa line is uncommented.

What is the use of spring boot framework?

Spring Boot helps developers create applications that just run. Specifically, it lets you create standalone applications that run on their own, without relying on an external web server, by embedding a web server such as Tomcat or Netty into your app during the initialization process.

You need add this dependency

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>

then it will work.

You have 0 compile dependencies, only test-compile dependencies defined, because you've commented out spring-boot-starter-data-jpa. Spring starter's pull other dependencies in (including other starters) to create everything needed at compile time. Un-comment the spring-boot-starter-data-jpa dependency, and/or re-evaulate what dependencies you actually want.
