Comment exécuter les tests JUnit Eclipse Plugin avec JMock?

Question

J'ai un plug-in Eclipse et des tests junit qui utilisent la bibliothèque jMock. Quand j'exécute mon test 'comme junit', tous les tests fonctionnent correctement. Mais quand je les lance « comme test de plugin JUnit » Je reçois l'erreur suivante:

Je l'ai corrigé. plug-in JMock, que je initialement créé, était la suivante:

plugin.xml:

<?xml version="1.0" encoding="UTF-8"?> 
<?eclipse version="3.0"?> 
<plugin 
id="jmock-2.5.1" 
name="JMockClasses Plug-in" 
version="1.0.0" 
provider-name=""> 

<runtime> 
    <library name="bsh-core-2.0b4.jar"> 
    <export name="*"/> 
    </library> 
    <library name="cglib-2.1_3-src.jar"> 
    <export name="*"/> 
    </library> 
    ... 
    <library name="jmock-2.5.1.jar"> 
    <export name="*"/> 
    </library>  
    <library name="jmock-junit4-2.5.1.jar"> 
    <export name="*"/> 
    </library> 
    ... 
</runtime> 
<requires> 
    <import plugin="org.eclipse.core.runtime.compatibility"/> 
</requires> 


</plugin> 

i. e. c'était juste une bibliothèque sur mon chemin de classe. Je l'ai changé à ce qui suit: META-INF/MANIFEST.MF:

Manifest-Version: 1.0 
Bundle-ManifestVersion: 2 
Bundle-Name: JMockPlugin 
Bundle-SymbolicName: org.jmock_2.5.1 
Bundle-Version: 1.0.0.qualifier 
Bundle-Activator: jmock.Activator 
Require-Bundle: org.eclipse.ui, 
org.eclipse.core.runtime, 
org.junit4 
Bundle-RequiredExecutionEnvironment: JavaSE-1.6 
Bundle-ActivationPolicy: lazy 
Bundle-ClassPath: bsh-core-2.0b4.jar, 
cglib-2.1_3-src.jar, 
cglib-nodep-2.1_3.jar, 
hamcrest-core-1.1.jar, 
hamcrest-library-1.1.jar, 
jmock-2.5.1.jar, 
jmock-junit3-2.5.1.jar, 
jmock-junit4-2.5.1.jar, 
jmock-legacy-2.5.1.jar, 
jmock-script-2.5.1.jar, 
objenesis-1.0.jar 

maintenant Eclipse OSGI classloader est capable de charger mon JMockPlugin et je n'ai aucun problème.
