here is a possible solution.
Create a lib folder in your project directory and put the jfxrt.jar into that directory.
com.oracle
javafx
2.2.3
system
${project.basedir}/lib/jfxrt.jar
And if you want to build an executable jar you only need to include the javafx-maven-plugin. For further information see: link-to-github
com.zenjava
javafx-maven-plugin
1.3
[put your application main class here]
