Ant PDE Tests Run with JUnit4

Hi,

I am trying to automate pde tests, using pde-maven-plugin, maven calls ant task. I followed instructions here:http://www.eclipse.org/articles/article.php?file=Article-PDEJUnitAntAutomation/index.html to create the test.xml

Tests failed, first because No Tests Found

junit.framework.AssertionFailedError: junit.framework.AssertionFailedError: No tests found in com.example.TestSuite
    at org.eclipse.jdt.internal.junit.runner.junit3.JUnit3TestReference.run(JUnit3TestReference.java:130)
    at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38)

I searched and found that I should use JUnit4Adapter, but doing that I got ClassCastException, here's the stack trace

java.lang.ClassCastException: junit.framework.JUnit4TestAdapter cannot be cast to junit.framework.Test

Here's my plugin dependencies:

Require-Bundle: org.eclipse.ui, org.eclipse.core.runtime, org.eclipse.jdt.core;bundle-version="3.4.2", org.eclipse.jdt.launching;bundle-version="3.4.1", org.eclipse.core.resources;bundle-version="3.4.1", org.apache.xerces;bundle-version="2.9.0", org.junit4;bundle-version="4.3.1"

and the test class

package com.example;

import junit.framework.JUnit4TestAdapter;
import junit.framework.Test;

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

@RunWith(Suite.class)
@SuiteClasses( { SimpleTests.class})
public class TestSuite {

    public static Test suite() {

        return new JUnit4TestAdapter(TestSuite .class);
    }

}

any idea how to fix?

It is fixed by adding next lines when invoking org.eclipse.equinox.launcher.Main:

<arg line="-testLoaderClass org.eclipse.jdt.internal.junit4.runner.JUnit4TestLoader"/>
<arg line="-loaderpluginname org.eclipse.jdt.junit4.runtime"/>

Here's the full java ant task:

<java dir="${plugin.dir}"  
    fork="yes"
    classname="org.eclipse.equinox.launcher.Main"
    classpathref="equinox.launcher.class.path"
    jvm="${jvm}">
    <arg line="-application ${application}"/>
    <arg line="-data ${test.reports.dir}/output/ws"/>
    <arg line="-port ${pde.test.port}"/>
    <arg line="-dev bin -clean -debug"/>
    <arg line="-testpluginname ${plugin.name}"/>
    <arg line="-testLoaderClass org.eclipse.jdt.internal.junit4.runner.JUnit4TestLoader"/>
    <arg line="-loaderpluginname org.eclipse.jdt.junit4.runtime"/>
    <arg line="-classnames ${test.classes.list}"/>
    <jvmarg line="${vmargs}"/>
</java>
