Reference to undefined variable env" error running Eclipse with TestNG/Maven

Getting the error 'Launching [testname]' has encounted a problem. Reference to undefined variable environment

Background: I have a test suite installed that I did not create or use before. When I initially run the test suite, there are no errors. I copied the body of a new test case, right clicked and created and named a new class and made one small change to try to teach myself how to run this test suite. I am new in this QA department and coming from Robot Framework/Python to a Page Object Model Java environment using Eclipse, Maven, TestNG. I have not made any path changes or environment changes except for trying to put maven in my path after mvn -version came up with nothing. My lead says that I shouldn't even have to screw around with maven because it worked when I ran the original set of test cases.

How do I figure out what undefined variable environment they're talking about? All the variables are defined in my program and the environment doesn't seem to be a problem with anyone else.
