Hi Surendar,
It seems your problems are due to a lack of familiarity with Maven. I recommend reading some basic Maven tutorials.
You may want to define the following environment variables:
MAVEN_HOME
M2_REPO
Another possible problem is if there is a proxy server in your environment, you will probably have to modify %MAVEN_HOME%\conf\settings.xml (this is the only situation in which I have had the necessity to modify this file).
Is your repostitory really at C:\Documents and Settings\surendar_sadhasivam\.m2\repository? Perhaps it is somewhere on the LAN.
Although I haven't tried to provide a complete answer to your problem, I hope this will lead you to the answers you need.
Good luck!
