I'm attempting to run a simple JUnit test case on version 3.7 of JUnit (I'm not able to upgrade this to the latest version)
Running IntelliJ, I get the following exception when I attempt to run my JUnit testcase :
Exception in thread "main" java.lang.NoClassDefFoundError: junit/textui/ResultPrinter

I have IntelliJ version 10.0.2, JUnit 3.7 on my classpath and the IntelliJ plugin which states it supports 3.x and 4.x
I can see IntelliJ executing the following (added breaks to make it more readable)

If I open up my Junit jar file that I'm using, under junit/textui I only have a class called TestRunner. This makes me think IntelliJ is trying to use the wrong version (i.e., not 3.7)
What can I try? I've Googled this but haven't had much luck
IntelliJ IDEA doesn't support JUnit 3.7. The minimum supported version is 3.8. Update your JUnit jar in the classpath and everything will be fine.
