Unable to Transfer spring-boot-starter-parent from maven repository - spring

Question

Below is my pom.xml.
I am getting exceptions while fetching the spring-starter-parent from maven repo.
what is it that I should specify in my relative path :
What I tried: Relative path as ../pom.xml, .., ../ All pointing to wrong as I understand that this jar file should be served over https then why we should give a relative path? As in my understating relative path is given when project is in the local and we need to specify the location of parent pom.xml.
For spring-starter-parent it to be served from "https://repo.maven.apache.org/maven2/org/springframework/boot/spring-boot-starter-parent/2.3.1.RELEASE/spring-boot-starter-parent-2.3.1.RELEASE.pom" we shouldn't need a relative path..
But as I am getting errors I tried those things as well.
Please help in letting me know what is wrong with the pom.xml
