Hi,

I'm having problems understanding how to configure AntRunner to write
its output to the Console.

I've added implemented a BuildLogger:
> package at.bestsolution.efxclipse.tooling.jdt.ui.internal.handler;
>
> import org.apache.tools.ant.DefaultLogger;
> import org.eclipse.ui.console.ConsolePlugin;
> import org.eclipse.ui.console.IConsole;
> import org.eclipse.ui.console.IConsoleManager;
> import org.eclipse.ui.console.MessageConsole;
> import org.eclipse.ui.console.MessageConsoleStream;
>
> public class AntLogger extends DefaultLogger {
> // the message console stream used to output to the console view
> // private MessageConsoleStream mConsoleStream = null;
>
> public AntLogger() {
> super();
> MessageConsole myConsole = findConsole("Some console name");
> // mConsoleStream = myConsole.newMessageStream();
> }
>
> protected void log(String message) {
> // mConsoleStream.println(message);
> }
>
> public static MessageConsole findConsole(String name) {
> ConsolePlugin plugin = ConsolePlugin.getDefault();
> IConsoleManager conMan = plugin.getConsoleManager();
> IConsole[] existing = conMan.getConsoles();
> for (int i = 0; i < existing.length; i++)
> if (name.equals(existing[i].getName()))
> return (MessageConsole) existing[i];
> // no console found, so create a new one
> MessageConsole myConsole = new MessageConsole(name, null);
> conMan.addConsoles(new IConsole[] { myConsole });
> return myConsole;
> }
> }

exported it into a .jar and registered this one using
org.eclipse.ant.core.extraClasspathEntries but now when running the
AntRunner I get a ClassCastException.

The problem is that the Logger is loaded through Class.forName() and so
there a 2 different BundleLogger.class-instance because there are 2
different classloaders.

Did I forget something to register?

Have you found a solution for this?
I tried to set this with setCustomClasspath but now he don't know the Console classes
Greetings,
Gerald
