That would help NUTCH-87 (whitelist urlfilter). The code is all in
one plugin, but there is a utility class that needs to be called from
the command line.

Hi,
I just found out that it's not possible to invoke main() methods of
plugins through the bin/nutch script. Sometimes it's useful for
testing and debugging - I can do it from within Eclipse, because I
have all plugins on the classpath, but from the command-line it's
not possible - in the code they are accessed through
PluginRepository. So I added this:
public static void main(String[] args) throws Exception {
NutchConf conf = new NutchConf();
PluginRepository repo = new PluginRepository(conf);
// args[0] - plugin ID
PluginDescriptor d = repo.getPluginDescriptor(args[0]);
if (d == null) {
System.err.println("Plugin '" + args[0] + "' not present or
inactive.");
return;
}
ClassLoader cl = d.getClassLoader();
// args[1] - class name
Class clazz = Class.forName(args[1], true, cl);
Method m = clazz.getMethod("main", new Class[]{args.getClass()});
String[] subargs = new String[args.length - 2];
System.arraycopy(args, 2, subargs, 0, subargs.length);
m.invoke(null, new Object[]{subargs});
}
It works rather nicely. If other people find it useful, I can add
this to PluginRepository.
