When I right click on my project and go to maven > add depedency it says "Artifact id cannot be empty". Basically i can't search for anything if i write "hibernate" it only shows 3 options (none including hibernate validator) yet if I write at group id: org.hibernate, artifact-id: hibernate-validator and version: 4.2.0.Final it knows what to download (i can find them under Libraries > Maven Dependencies.
Anyone knows why this happens?Thank you. I forgot to mention i'm a beginner regarding Java EE and Maven etc.
