Hi,

I don't think if there is a way to verify the settings.xml (someone can 
correct if I am wrong). You can turn on the DEBUG level for continuum 
and see what settings.xml it logs on the console in the scenario where 
this error occurs.

I ran into same error few weeks ago and ended up reverting the 
settings.xml to a sane revision and then making small incremental 
updates to it.  Is that new repository location missing a property like 
- id, name?

Cheers,
Rahul
