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?
