I am stuck trying to add org.nakedobjects.prototyping: the indexer app cannot find anything. I realized that the url textbox does not contain the address http://repo1.maven.org/maven2/, any clues?
I am using latest eclipse 3.4.2
Are you using Maven 2.1.0 correctly? I had the same problem in my Ubuntu box and I think it is a bug. I solved it with Maven 2.0.10
