Custom plugin successfully registered but not executed.

[Alaak]

Hi,

I am trying to create a very simple Nutch plugin that simply prints 
something to the command line or hadoop.log during execution. I followed 
the tutorial on setting up Nutch in Eclipse from the Wiki and also the 
Tutorial on creating a simple Plugin. I also found another Tutorial 
here: http://florianhartl.com/nutch-plugin-tutorial.html#comment-41 and 
followed that as well.

After some problems I finally managed to get Nutch up and running and my 
Plugin to be registered according to hadoop.log

2012-08-12 21:36:48,578 INFO  plugin.PluginRepository -     Add Field to 
Index (myPlugin)

However, regardless of what I am attempting I seem to be unable to make 
the plugin actually run. It seems to not be executed. There was a guy 
having the same problem in the comments of the second tutorial I 
followed and since I am developing under Linux it might be possible that 
my problem is related to the following: 
http://lucene.472066.n3.nabble.com/Nutch-plugin-ignored-in-linux-works-on-windows-td3191884.html

However none of these questions got an answer up to now? So has there 
been some new insight on running custom plugins under Linux (actually 
Ubuntu 12.04) or could it be something completely different? Any ideas?

I would absolutely willing to provide you with additional information if 
you could tell me what you need.

Regards
