Did you add the LWJGL 3 jars to the modulepath or to the classpath? This is a typical problem starting with Java 9, where - in besides the classpath you now have the modulepath. And Eclipse will (when you answer with "yes" in the new project wizzard about whether it should create a module file) create a module-info.java file. In this case, your application is a module and you must also declare the dependencies in your module-info.java file.
