Can't launch glfw

[Ryan48]

I'm new to lwjgl. I was trying to simply create a window. However I do not understand how to resolve this exception

here is the message
Exception in thread "main" java.lang.NoClassDefFoundError: org/lwjgl/glfw/GLFW
   at com.tianyuan.flappy.Main.main(Main.java:9)
Caused by: java.lang.ClassNotFoundException: org.lwjgl.glfw.GLFW

   at java.base/java.lang.ClassLoader.loadClass(ClassLoader.java:521)

can anyone help me?

How to solve this entirely depends on how you invoke the java command, whether you use an IDE and which one you use, whether you use the Java 9+ Module System or the classpath and whether you use a Java build system (like Maven, Gradle, Ant+Ivy).
