I am a beginner for spring boot. I followed the getting started guide. It was not successful. After that I import a project from this link
http://www.springboottutorial.com/introduction-to-jpa-with-spring-boot-data-jpa.
It gives this error
"Project build error: Non-resolvable parent POM for com.in28minutes.springboot:H2InMemoryDbDemo:0.0.1-SNAPSHOT: Failure to transfer org.springframework.boot:spring-boot-starter-parent:pom:2.0.0.RELEASE from https://repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced. Original error: Could not transfer artifact org.springframework.boot:spring-boot-starter-parent:pom:2.0.0.RELEASE from/to central (https://repo.maven.apache.org/maven2): connect timed out and 'parent.relativePath' points at no local POM"
I think i have missed some important configuration.
Thank you
