[swtbot-dev] NoClassDefFoundError for a class in runtime plugin dependen

[Jordi Fernandez <jordi.fernandez@xxxxxxxxxxxxxxx>]

I'm developing a test with SWTBot that is throwing NoClassDefFoundError when trying to load a class that is present in a runtime plugin dependency.

I'm using Eclipse 3.4.2. My workspace has several plugin projects for the product under development plus the SWTBot test plugin. Initially I code a simple test which just clicked in a menu. It runs fine:

---------
public void menuTest() throws Exception {

    bot.menu("A").menu("B").menu("C").click();

 }
----------


Then I tried to access a custom developed widget using the following code:


----------------

public void menuTest() throws Exception {
    SWTBotPreferences.TIMEOUT = 10000;
    bot.menu("Aplicacion").menu("Comercial").menu("Posición Global").click();
    System.out.println("Hola");
    
    Matcher matcher = allOf(
            widgetOfType(ComboSearchSelector.class)             
          );
    
    ComboSearchSelector combo = (ComboSearchSelector) bot.widget(matcher);
    assertTrue(combo.getItemCount() > 0);
}

--------------------

This second test fails with a NoClassDefFoundError for the ComboSearchSelector class. This class is in one of the plugin projects of my workspace and is included as a plugin to load in the run configuration (as it is a required plugin for the product under development) . In order to compile my test, I added this plugin project as a project dependency in the java build path.

How come I'm getting a NoClassDefFoundError at runtime when the referenced class is loaded (because the plug-in that holds it is present at runtime)?

Thanks in advance.
