Yes, classpath specified and definitely includes junit.

When I run it with verbose, junit prints out the classpath it is using: it 
definitely includes the junit jar, and definitely doesn't include any of 
the ant jars.

It really looks as if it's the 
org.apache.tools.ant.taskdefs.optional.junit.JUnitTestRunner class that 
isn't being found because it's not in the class path: which it isn't, as 
the ant jars aren't there.

So should I be specifying the ant jars in my own class path?  That really 
doesn't seem as if it should be right.

Note that the problem above occurs when I specify fork="yes"
When I do fork="no", I get
java.lang.NoClassDefFoundError: junit/framework/TestListener
         at 
org.apache.tools.ant.taskdefs.optional.junit.JUnitTask.executeInVM(JUnitTask.java, 
Compiled Code)
         at 
org.apache.tools.ant.taskdefs.optional.junit.JUnitTask.execute(JUnitTask.java:283)
         at 
org.apache.tools.ant.taskdefs.optional.junit.JUnitTask.execute(JUnitTask.java, 
Compiled Code)
   [stuff omitted...]

This time it looks like it *is* a junit class that it can't find, but again 
the verbose output says that the junit jar is in the classpath.

I really don't understand what is going on here!

(and why do I have to use taskdef to set up the junit task when it's meant 
to be a default one?)
