Sebastian Nagel resolved NUTCH-2591.
------------------------------------
    Resolution: Not A Problem

Hi [~usama_], this is a bug tracker not a support forum. Please ask for help on the [Nutch mailing lists|http://nutch.apache.org/mailing_lists.html]. The [Nutch wiki|https://wiki.apache.org/nutch/] also contains documentation how to setup a Nutch development environment. The short answer: dependencies to external libraries are registered and managed in ivy/ivy.xml. Note that there is already a plugin "language-identifier". It's not based on GLD2 but you may take it as an example how to integrate language detection. Thanks!

> I am modifying Nutch 2.3.1 and integrating CLD2 language detector in *FetcherReducer.java* class. I made a separate class name *LangInfo.java* in *org.apache.nutch.fetcher* package.
> In this LangInfo.java class i tried to write import org.json.simple.JSONObject;
> and org.json.simple.parser;
> but when i build it using *ant runtime* command in Nutch directory it fails with error
>  
> *src/java/org/apache/nutch/fetcher/**LangInfo**.java:20: error: package org.json.simple.JSONObject does not exist*
>  
> *src/java/org/apache/nutch/fetcher/**LangInfo**.java:21: error: package org.json.simple.parser does not exist***
>  
> But when i open it in eclipse, eclipse does not shows error on this import. and if i go to project properties > Libraries there i found *json-simple-1.1.0.jar.* it means this jar file already exists. but why i am always getting errors due to this import?
> i have attached two screenshots with this issue:
> 1- jar.png (this is eclipse screenshot showing json-simple-1.1.0.jar exists)
> 2- error.png (this is terminal build error log. when i run ant runtime command)
> Kindly help me ASAP.
> TIA.
