I think I know what caused this and just committed a fix. Should be in tomorrows 2.6.3-SNAPSHOT.
Basically, to support m2e, we started sending all the warnings and errors into the BuildContext object that m2e will provide. That way, the warnings and errors and such can properly be marked in eclipse editors and such. However, that API requires a "File" object. We were taking the systemId of the WSDL and pretty much just creating a File object from it. In your case, the systemId is an HTTP URL and thus a File is not usable so the file ends up as null. m2e is apparently not liking the null file object. I *THINK* I now have it fixed enough. It kind of creates a fake File object for the HTTP url that allows the proper warning to display on the command line maven. Not 100% sure in m2e right now. If you could give it a try, that would be great. That said, you could also add <fork>true</fork> to the config for the plugin and it should just fork it in which case we cannot really pass the errors back to m2e anyway. That may work around it.
