问题
I have been developing a Python program using the Pydev(2.5.0) plugin in Eclipse Helios on Ubuntu OS 11.4.
The program uses lucene (core 3.6) library. Lucene was installed using jcc.
Previously I developed it with a text editor and ran on the command line using python xxx.py and there was no problem regarding lucene libraries.
Then, I imported the project to Eclipse IDE. The other source files still run as-is, but the program cannot locate the basic classes of lucene library.
import lucene # no error
but if I try to import StandardAnalyzer or any other class, I get an error:
from lucene import StandardAnalyzer #error: unresolved import
My configuration:
Grammer Version: 2.7
Python interpreters: usr/bin/python2.7
Libraries include:
I tried the add the lucene folder to the external libraries but it didn't help. I have found this path by using command line python interpreter with these commands.
import lucene
print lucene.__path__
Though a similar path is already in the library (see image. 2nd library)
['/usr/local/lib/python2.7/dist-packages/lucene-3.6.0-py2.7-linux-i686.egg/lucene']
I would appreciate your comments about this problem. Thanks.

I think that the problem is that the PyDev code-analyzer can't really analyze PyLucene. You can try adding 'lucene' to window > preferences > pydev > interpreter - python > forced builtins (see: http://pydev.org/manual_101_interpreter.html for details).

Had the same problem running Helios Service Release 2 on Mac OSX 10.8.5. Fixed it as follows:
Open Project >> Properties
- Select PyDev - Interpreter/Grammar
- Click "Click here to configure an interpreter not listed"
- Select your interpreter
Select "Forced Builtins" and add all three directories (lucene, org and java) (see http://pydev.org/manual_101_interpreter.html for details).
- Select "Libraries" and add the path to each of those directories to System libs.
