Unable to run simple JUnit TestCase on old version of JUnit

Question

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
    at java.lang.Class.forName0(Native Method)
    at java.lang.Class.forName(Class.java:169)
    at com.intellij.rt.execution.application.AppMain.main(AppMain.java:108)
Caused by: java.lang.ClassNotFoundException: junit.textui.ResultPrinter

    at java.lang.ClassLoader.loadClass(ClassLoader.java:248)
    ... 3 more

Process finished with exit code 1

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

Answer 1

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.
