Ant JUnit Task could not find junit / framework / TestCase.class

Question

I am trying to run a JUnit 4.8.1 task in Ant 1.7.1. My IDE is Eclipse Helios. I’ve been banging my head on a brick wall for two days now and I can’t understand it. I am sure that I am reading other posts, this is a problem with the classpath, but I do not see where I am mistaken.

My JUnit4 test suite is defined as follows:

package mypackage.tests;

import org.junit.runner.RunWith;
import org.junit.runners.Suite;

/**
 * JUnit 4 Test Suite for the entire <code>mypackage</code>
 * package
 */
@RunWith(Suite.class)
@Suite.SuiteClasses({ mypackage.tests.controller.AllTests.class })
public class AllTests {
}

... simple enough, but the test failed with a ClassNotFoundException

java.lang.ClassNotFoundException: mypackage.tests.AllTests
 at java.net.URLClassLoader$1.run(Unknown Source)
 at java.security.AccessController.doPrivileged(Native Method)
 at java.net.URLClassLoader.findClass(Unknown Source)

 at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source)
 at java.lang.ClassLoader.loadClass(Unknown Source)
 at java.lang.Class.forName0(Native Method)
 at java.lang.Class.forName(Unknown Source)

When I turn on the debug flag, I get the following trace from Ant:

(...)

Loaded from C:\eclipse\plugins\org.junit_4.8.1.v4_8_1_v20100427-1100\junit.jar junit/framework/Test.class

Obviously, the JUnit jar is in the classpath, and other classes such as Test.class are compiled, so why do I get the message "can't find TestClass.class"?

I tried adding JUnit.jar to the Ant class path in the Eclipse GUI, and this has the following effect:

(...)
