As per the installation instructions, JCC is successfully built.

Dependencies Installed were: ant, openjdk-7-jdk, python-setuptools, python-dev.

Then procedding to make pylucene, in "Makefile" i choose specs corresponding to Ubuntu 11.

# Linux     (Ubuntu 11.10 64-bit, Python 2.7.2, OpenJDK 1.7, setuptools 0.6.16)
# Be sure to also set JDK['linux2'] in jcc's setup.py to the JAVA_HOME value
# used below for ANT (and rebuild jcc after changing it).
PREFIX_PYTHON=/usr
ANT=JAVA_HOME=/usr/lib/jvm/java-7-openjdk-amd64 /usr/bin/ant
PYTHON=$(PREFIX_PYTHON)/bin/python
JCC=$(PYTHON) -m jcc --shared
NUM_FILES=8

On executing "sudo make" command following error was encountered:

On searching for the error few old mailing list were found which had similar errors but i was not able to get any hint out.

Can you please let me know what went wrong and how to fix it?

Do I need to install the java Lucene before installing pyLucene?

Yes, you do need Lucene before you can use PyLucene. - PythonNut
In fact, it appears that that is your problem. Symbols from the error (Namely, NoSuchMethodException among others) seem to indicate that JCC cannot fine Lucene's methods. Are you sure it's installed? - PythonNut
in case you are not limited to pylucene, but need just some search lib, have a look at whoosh. doesn't need java, pure python. - Thomas Waldmann
ask it on askubuntu.com - OnlyMAJ

Following these instructions (http://bendemott.blogspot.de/2013/11/installing-pylucene-4-451.html) got my system installed with pylucene. Before it was working, it was crazy and I had this problem (Building Pylucene on ubuntu 14.04(trusty tahr)) but after a thorough reformatting and a fresh ubuntu 14.04 i got it running:

# Downloads and extract pylucene
$ wget http://mirror.serversupportforum.de/apache/lucene/pylucene/pylucene-4.9.0-0-src.tar.gz
$ tar -zxvf pylucene-4.9.0-0-src.tar.gz

# Install dependencies
$ sudo apt-get install ant
$ sudo apt-get install g++
$ sudo apt-get install python-dev
$ sudo apt-get install python3-setuptools
$ sudo easy_install pip
$ sudo pip install setuptools --upgrade 

# Build and install pylucene
$ cd pylucene-4.9.0-0/jcc
$ sudo python setup.py build
$ sudo python setup.py install 
$ cd ..

Edit the file named "Makefile" located at the root of the pylucene-4.9.0 directory you just extracted and locate this line:

# Linux     (Ubuntu 11.10 64-bit, Python 2.7.2, OpenJDK 1.7, setuptools 0.6.16)

Uncomment lines in the Makefile as shown (if you are on linux) and save the changes:

enter image description here

Then continue with:

$ make 
$ sudo make install  

Voila, it's installed. To test that pylucene works:

$ python
>>> import lucene
>>> lucene.initVM()
