With a Maven 3 based project in NetBeans 8 beta, when I context+click on the "Dependencies" item of the "Projects" navigator and choose "Add Dependency…" menu item, I get a dialog box for searching the repository.

Every time I type in "slf4j-api" and choose the found item "org.slf4j : self4j-api", I get different results. Sometimes in the list of versions I get 1.7.0, sometimes 1.7.5, but never the latest: 1.7.6 available for download from the [slf4j download page](http://www.slf4j.org/download.html).

Why does the list change when I search and display a list a minute later?

So I got try a search for "logback-classic", and click on "ch.qos.logback : logback-classic". The greatest version number is 1.0.13. That was released in May of last year. Since then version 1.1.0 was released 2014-01-28, and 1.1.1 on 2014-02-05. 

Why does Maven not offer these later versions?

Is it a caching problem? Is there some way to force the dialog in Netbeans to update its list of available versions?
