Thank you very much your support. I merged the changes which Johannes did.
I started building process by cloning the recommenders git repository[1] again. Cloning was successful.
Then i went to local repository directory(org.eclipse.recommenders) and execute the command mvn clean install.
I am getting this error now (following is the part of the trace form the beginning). I am using Windows 7 platform.
