How can I define environment variables for a Java project in NetBeans?

Question

I need to define environment variables for my project since I will eventually want to deploy it to Heroku, or any other PaaS. What I am having trouble with is run the application from the NetBeans IDE with my environment variables.

Where can I enter them so I can test them? I use environment variables for MongoDB URI, different API keys, etc.

Edit: I am using OSX 10.10.2 with NetBeans 7.4.

I tried looking at this discussion but my version of NetBeans lacks the Set Properties: Add in the Run dialog.

You should look in the Actions dialog, not in Run. There you select 'Run project' and then click the Add button.
