Hi,
I have a simple plugin that use the pluginFirstClassLoader with the
following Plugin and ItemListener classes:
public class PluginImpl extends Plugin {
private final static Logger logger =
Logger.getLogger(PluginImpl.class.getName());
private String attribute;
@Override
public void start() throws Exception {
logger.log(Level.INFO, "PluginImpl started");
attribute = "someValue";
}
public String getAttribute(){
return attribute;
}
}
public class ItemListenerImpl extends ItemListener {
private final static Logger logger =
Logger.getLogger(ItemListenerImpl.class.getName());
@Override
public void onLoaded() {
String value =
Jenkins.getInstance().getPlugin(PluginImpl.class).getAttribute();
logger.log(Level.INFO, "pluginImpl attribute value is: " + value);
}
}
If I deploy this plugin in Jenkins, it works as expected: PluginImpl start
method get called and set "someValue" in the attribute, ItemListemerImpl
get called when all the jobs are loaded and it is able to retrieve the
PluginImpl singleton and print the value of the attribute.
The problem is that if I use HusdonTestCase or JenkinsRule, I get a NPE in
the ItemListener.onLoaded method because
Jenkins.getInstance().getPlugin(PluginImpl.class) return null. I inspected
the pluginManager while debugging the test and it contain my plugin. The
reason why the method is not returning my plugin is that PluginImpl.class
is loaded by 2 different class loaders.
When Jenkins test instance initialize my plugin, PluginImpl is loaded by
PluginFirstClassLoader but when ItemListenerImpl.onLoaded is called,
PluginImpl is loaded with by sun.misc.Launcher$AppClassLoader.
Any idea on how to fix Jenkins tests harness to use proper classloader?
Thanks
