Address Book example -- failure to transfer...

Any suggestions greatly appreciated.

I am importing the Maven git version from
https://github.com/vaadin/addressbook.git

Failure to transfer org.apache.maven.plugins:maven-surefire-plugin:pom:2.12.4 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.apache.maven.plugins:maven-surefire-plugin:pom:2.12.4 from/to central (https://repo.maven.apache.org/
maven2): repo.maven.apache.org

Found solution:

Run → Maven clean
Run → Maven install
