I tried building https://github.com/Sanne/ogm-kitchensink (as711 branch) locally but got an error: Caused by: org.sonatype.aether.resolution.ArtifactResolutionException: The repository system is offline but the artifact org.hibernate:hibernate-search-orm:jar:4.1.1.Final is not available in the local repository.
