Hey,
I've been trying to run my tests headlessly in anticipation of running them off of a remote Unix box in the future. So I've gotten a decent start to Ant, but when trying to run my first tests I've been running into some errors:
java.lang.UnsupportedClassVersionErrors: <my testclass> : Unsupported major.minor version 8243.8224
I've been running over this for about 2 hours no and no closer to a solution. I thought it might be something to do with not being able to import my .jar files but I think I ruled that out, although don't take my word on it. Right now my thoughts are it is some kind of error in the compiled class. See I compiled my class in Eclipse and then copied it to an external directory to emulate what is actually going to happen when I start running off the Unix box. Dunno if this is the cause though. Any help is appreciated!

Hi Greg,
--
This usually happens when you try to run a class compiled with javac version N with a java version <N. However, the numbers you are giving are surprising (they should be around 49).
I suspect your .class files have become corrupt somehow.

Yeah right, I'm pretty sure that might have been what was screwing me up:
A. I had exported my tests from Eclipse, but I never actually modeled my Eclipse file structure in my ant project, even though I had compiled in Eclipse, so I was messing around with the compiled file to try to get my class file to run in my new file structure
B. I had compiled with JRE7 in Eclipse. I changed my JRE system library to JDK1.7 and then compiled using that.
When I compiled using the JDK and changed my project directory to look like my Eclipse workspace, and didn't change the compiled file, everything worked.
