Description

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.
