Invoking Maven and having it ignore your local settings

I recently found myself working remotely from my network and needed to perform a build using Maven. My ~/.m2/settings.xml file is configured with information about my network's Nexus repository and a few other things. I therefore needed to find a way to tell Maven to ignore my regular settings; preferably without mutating my settings.xml file. In particular I just wanted to have Maven pull out a plugin from the Central repo.

The documentation on the Maven command doesn't mention how it can be invoked to ignore your settings.xml. However if you type the following then it will ignore it (in my case I wanted to download the wonderful Cobertura plugin and produce a code coverage report) :

mvn -s/dev/null cobertura:cobertura

All good.
