Hi

Obviously You didn't include necessary references to other JARs or source
directories. It's configured in plugin.xml
Check the file and add there all necessary references. Remember that each
plugin is compiled separately and it doesn't know about other plugins.
Compare your ANT files with files from other plugins. Maybe it will give you
a hint.

I'm trying to add a new plugin to Nutch/Solr for having new fields and
finally searching about it in the terminal interface.

For that , i have readen the howto WritingPluginexample 0.9 from the

This problem like cames from packages and ant can't import classes from
other packages .

Can anyone help me please what i must do for resolving this problem ????

Here is a copy of results of ANT building :
