How to overwrite maven central resolver

How can I overwrite the central maven resolver

trying to execute
`%classpath config resolver repository.central https://repository.my.corp.com/repository/myRepo
`
does not seem to do the trick.

I need to overwrite the central resolver to a corporate proxy repository!

Also can I turn up the log level to debug this, i.e. see the URLs it tires to connect to?

# edit
Neither `central` nor `central-proxy` work to override the key for the central repository

Even when setting up a custom `~/.m2/settings.xml` file which would configure the proxy for regular maven usage it will not work.
