Your pom is more important here than your code

Try these:

1.Follow below steps:- Window --> Preference --> Installed JREs -->Change path of JRE to JDK(add). Also make sure the jdk version in your POM is same as that of java compiler you have.

2.Did you check the directory path in which your project is located. May be it has access restrictions.

3.Check your internet connection, whether you are able to reach https://repo.spring.io .
