When I click on "Clean and Build" NetBeans generates a .jar file and inside the folder "dist" it add a directory called "lib" with all the java libraries used to implement the program. I would like to achieve with this IDE an unique .jar file that includes everything you need such as Eclipse does by default. Is it possible?
