I added JFoenix to eclipse and SceneBuilder. It works in SceneBuilder but while compling the project leads to ClassNotFoundException

The scenebuilder is able to find the jphoenix library, but your project / the java codes that you wrote cannot find the jphoenix library. That is why you are getting the ClassNotFoundException. So to fix this, you have to import the jar file in your project. I don't use eclipse myself, so I myself don't know how to do this. A quick google revealed this answer:

how-to-import-a-jar-in-eclipse

According to this, You can add a jar in Eclipse by right-clicking on the Project → Build Path → Configure Build Path. Under Libraries tab, click Add Jars or Add External JARs and give the Jar. Maybe this will help. Once imported, your project should compile properly. Good luck.
