Now I have tried updating the repository ect but I am having no luck.
Upon suggestion I have tried to update the plugin registry but there is no such file pugin-registry.xml on my file system.
Also it builds fine within eclipse but fails from command , so I'm guessing they are both using different versions. How to fix this?
Try using the -cpu flag. Output from mvn -help:
usage: mvn [options] [<goal(s)>] [<phase(s)>]
Options:
-cpu,--check-plugin-updates Force upToDate check for any
relevant registered plugins
You are missing a plugin required for the Maven build to function. Check and tweak the values in the Plugin Registry such that an update is forced. You can also use command line parameters to force the download of the plugin.

I followed below steps and it worked for me. Check if it is useful for you.
project-->properties-->Maven-->User settings
change user settings to point out to correct settings.xml and to your repository folder should exist in your system.
This is resolved when I moved back to maven v 3.0.4.
