JFXtras ClassNotFoundException on maven build - eclipse

Question

I am using Eclipse with the Maven integration and included JFXtras in my project. When I do the maven build, it successfully creates the jar, but when I try to run it, I get a
java.lang.ClassNotFoundException: jfxtras.scene.control.ListSpinner
I integrated jfxtras like described here:
http://mvnrepository.com/artifact/org.jfxtras/jfxtras-labs/8.0-r3

Any ideas / help?

JFXtras consist of a number of artifact; labs, controls, common, ..., with some dependencies between them. The dependency for labs is missing. The pom below works for me.
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

That is for a release, if you want to use a snapshot, you need to add the Sonatype snapshot repository in the pom or .m2/settings.xml
