title: How can I run the IntelliJ debugger on unit tests in a Maven project?
body: <p>I'm working with a multi-artifact Maven project where artifacts in the project have a few dependencies on each other.  I am using IntelliJ 9.  I'd like to be able to set breakpoints in my unit tests, but when I right-click on the unit tests folder for my artifact and choose "Debug 'All Tests'", I get a Class not found exception referring to a class in a separate Maven artifact.</p>
  
  <p>I can run the Maven "test" goal on the parent artifact and it works fine.</p>
  
  <p>Any ideas?  Thanks.</p>
