Pavithra,
It looks a problem with downloading the Maven archetypes.
1. Are you behind a firewall or proxy? If yes, then you need to create a file called settings.xml in [user home]/.m2
directory and add in the proxy information: http://maven.apache.org/settings.html
2. You can also try deleting the .m2 directory and restart the IDE. Maven will attempt to download the archetypes again. It will take some time for them to download.
3. Please also telnet repo.maven.apache.org [port number] to rule out networking issues.
Can you please clarify if you have installed any of the Genuitec products like Angular IDE, CodeMix etc in Eclipse? If you are working only with Eclipse, then I suggest you cross post to development related forums like stackoverflow.com for further help with Eclipse + Maven.
Hope this helps. Please let us know if you have any further questions.
