----------------------------------------------------------------------
The ant command should build the files. But, am receiving the errors.

I am using Ubuntu 10.10. I am trying to run Genetic algorithm code. When i try 
to build the aima-core , using ant i am unable to do it. I am getting this 
error. 
I am using the latest(Nov 05 th release) aima-core available online. 

I have to change the encoding .. but am not sure where should I change how to 
Change.. I am really new to programming.. If anyone could explain me clearly 
using the commands should be used and files to be edited , thats really 
helpful!!! please ...

Hi arun.nurak,

As an immediate fix for your local copy just edit the file:

/home/arun/Downloads/aima-core/src/main/java/aima/core/agent/Action.java

and remove the 14th line, where there are character encodings that are not 
recognized on that platform. If you get similar errors and they are in comment 
blocks then just do the same thing. I will remove them from the main source. 
Thanks for the detailed bug and let me know if you've any additional questions.

Ciaran
