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?

Answer 1

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
