How to create a library in NetBeans

Question

I have a class Utilities.java that I'd like to turn into a library that I can include in subsequent projects.

I did New project, Java class library and named the class Utilities and put it into the C:\Users\Dov\Google Drive\NetBeansProjects\Utilities folder.

In a new project, I tried to add the library via Libraries, Add jar/folder and gave the name C:\Users\Dov\Google Drive\NetBeansProjects\Utilities\dist\Utilities.jar, so under Libraries I then had JDK 1.8 and Utilities.jar.

But I got errors (cannot find symbol) on all attempts to use methods in Utilities.jar.

What should I have done?

1.) Are you using imports for your Class </br>2.) Is your class and method PUBLIC? </br> 3.) Open up your jar file with a compression utility like WinRar and see if class is there? If yes then in correct package structure? — Ankit Srivastava

Refer to my Answer below. Not sure what was wrong with original approach, but I'm OK. So, yes, I was using imports of public classes. — DSlomer64

OK. I deleted Utilities.jar from the Libraries folder, then right-clicked Libraries and this time selected Add library..., which opened dialog in which I clicked Create library.

I gave the new library the name Utilties and clicked Add jar/folder,then gave path to jar file: C:\Users\Dov\Google Drive\NetBeansProjects\Utilities\dist\Utilities.jar. Now I have in the Libraries folder a library named Utilities - Utilities.jar and all is well.
