Hi Erick, thank you so much or the help and support.
As you have mentioned I have made the svn set up and while trying to connect using check out option am getting this error; C:\bin>svn co https://svn.apache.org/repos/asf/lucene/dev/ svn: E175002: Unable to connect to a repository at URL 'https://svn.apache.org/r epos/asf/lucene/dev' svn: E175002: OPTIONS of 'https://svn.apache.org/repos/asf/lucene/dev': could no t connect to server (https://svn.apache.org) Is this anything to do with the firewall set up? please advice me on the further steps.
