Mate, There are multiple things that you can do.

  • Check the maven repository for the jar of spring-boot-starter under org > springframework > boot

  • Sometimes the download might be interrupted or may be due to failure it would not have downloaded correctly, in that case delete the spring-boot-starter under org > springframework > boot and build again

  • You can clean and verify the maven project again (I would suggest to do this from the console, to do this go to the folder where your pom.xml exist and execute mvn clean verify)
