Running Nutch in Eclipse
nutch users,
I am having problems making modifications to the PruneIndexTool using
Eclipse from the nutch-0.8.1 release. I am able to import files into
Eclipse, thanks to this tutorial:
http://wiki.apache.org/nutch/RunNutchInEclipse
What I have run into is that Eclipse does not recognize the inheritance
from the other nutch classes. When a class is called to define a
variable, i get an error message: "*class* cannot be resolved to a
type". Some of this may stem from the inability to import packages: "The
import org.apache.lucene cannot be resolved"//one example//
More specifically, all classes have this sort of problem:
public boolean isPrunable(Query q, IndexReader reader, int docNum)
throws Exception{
Document doc = reader.document(docNum);
String url = doc.get("url");
//Error: Query cannot be resolved to a type
//Error: IndexReader cannot be resolved to a type
//Error: Document cannot be resolved to a type
Eclipse Properties:
I have followed the tutorial and have a build path with the conf/
directory. Under the java build path I have included as sources all the
files in the nutch directory. Each pull down tab has:
Included: (all)
Excluded: (none)
Native library location: (none)
Under Projects tab in the build path I do not have anything when I try
to add a project there are no projects to add.
Libraries include the two .jar files added from the tutoiral:
http://nutch.cvs.sourceforge.net/nutch/nutch/src/plugin/parse-mp3/lib/
http://nutch.cvs.sourceforge.net/nutch/nutch/src/plugin/parse-rtf/lib/
and the system library.
The Order and Export tab has all the nutch folders with its plugins.
If you could direct me to be to be able to resolve these variables and
allow Eclipse to inherit each class in the nutch directory, it would be
much appreciated.
~Jon

I was able to add you suggested .jar files and thankfully decreased the
number of errors from 5000 to 33. I think I'm still missing a couple
that I'm not aware of.
thank you,
~Jon

thanks for your help I was able to run nutch in eclipse. I included the
lib/, plugin/ and conf/ directories in the class path, as well as the
default eclipse plugins. I also made sure the only source folder was the
where I was saving the project.
thanks again,
~Jon

Required lib were not added to eclipse,try to add all the jar files in "<NUTCH_HOME>/lib" directory.
You can also refer the "bin/nutch" script for the jar file list required by nutch..
