Need help with MAGE execution error

Successfully built MAGE with "mwn install". Upon execution of mage-client.jar, or the .exe, I get the following error:
Could not find the main class: mage.client.MageFrame. Program will exit.
Any ideas?
I noticed that the mage.client.jar did not have the "main.class" or "lists.class" included in the compiled jar. Perhaps I have an issue with my Maven installation?
