Debugging Maven error settings [m2]

I am having trouble understanding the error below. Maven seems unable to
pull things down from the central repo, and I don't know why. 

I can connect to the repo via the web. 
I have deleted by ~/.m2/repository directory. 
The plugin-registry.xml files do not exist.
I have been playing with the settings.xml files, but I think I've undone
my changes. I would like to run the goal help:effective-settings, but I
can't download the maven help plugin. Catch-22.

Any ideas about what is going on? Or how to debug this type of
situation?

Assuming you have nothing special in your settings.xml or your hosts
file that would redirect things, a simple mvn help:effective-pom
should give you an idea as to what repos are being searched.

If you do have mirrors etc in settings.xml which complicate things, or
you just can't figure it out, then you might want to use a TCP/IP
analzer like Ethereal.

No this doesn't help. Is there anyway to see which repos maven is
checking?

Thanks,

You may be running into the default once-per-day check for updates.
If it fails once, Maven won't check [that repository for that plugin]
again until tommorrow.

Try adding -U to the command line.  (Or deleting the plugin directory
from your local repo.)

You may be running into the default once-per-day check for updates.
If it fails once, Maven won't check [that repository for that plugin]
again until tommorrow.
