The release plugin calls other plugins during its run, amongst them the 
deploy plugin. The "arguments" is to pass that to the deploy plugin as 
you suspected.

We might need to add a release-plugin configuration for this in a 
component or the parent. Need to play around with this a bit.

Fair enough. Do we agree that we should ditch the dummy repo from

This is configured in commons-parent-5 in the "rc" and "release" 
profiles, so you don't need to do *anything* in a component. The plugin 
is specifically for making sure that all artifacts include mandatory 
organization resources. The ASF has a special resourceBundle that 
includes the appropriate licensing files.
