You have to download maven central index. Settings/Maven/Repositories, choose repository and click Update. It'll download huge file and then autocomplete will work.

Though honestly I never use this feature, I prefer to research library website or, if I'm looking for a latest version, use something like search.maven.org , it might not be the fastest way, but I'll be sure that I use correct version. Maven repository contains some outdated duplicates for popular library and it might not be obvious.

I've done that - it still doesn't display properly.

Like I said, I've played around a bit with it in Netbeans and Eclipse and I'm familiar with the idea of downloading the index before I can search. I can't make it work properly in IntelliJ. Is there a Youtube video of an install->index->download workflow somewhere?
