JMonkeyEngine in Intellij IDEA

I have this pom.xml which is not working. It is impossible to use jme3 with maven. It is also not possible to use jme3 with jar:s, because the jar:s are not available, so nothing is possible.

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

It looks to me like the 3.1 version is currently in beta, and the correct version number for the most recent beta is 3.1.0-beta1. Also, it appears that the maven artifacts are available on JCenter since 3.1.0-alpha2 (https://bintray.com/jmonkeyengine/org.jmonkeyengine/jme3-core/view). The private repository seems to no longer exist.

Given that, I was able to get the following to work:
