In NetBeans, Ivy dependencies used at compile time, but not runtime

Question

I am new to NetBeans (version 7.2), and am trying to configure it for use with a project whose dependencies are configured with Apache Ivy. I have installed the Ivy plugin, modified my ivy.xml file to match the expected configurations ([compile, runtime, compile-test, runtime-test]. The project builds cleanly, and the appropriate libraries are present in the "Ivy Libraries/Runtime" project tree. However when I try to run the application in NetBeans, I get NoClassDefFoundError on classes that were imported by Ivy.

I assume that, somehow, I need to explicitly tell NetBeans to use the Ivy Libraries at runtime. But I can't figure out how to do it. Please stackoverflow, you're my only hope.

Answer 1

The primary problem is that I was just hitting the "run" button on the project. I'm not sure what class it was trying to run. But when I selected the actual class containing my main() method, and explicitly ran that one, it worked (or rather, it failed in a sensible way).
