I wanted to try out Apache Maven 2 today. So I started off with the tutorial and created a default project. After some playing with targets and plugins, a connection to http://repo1.maven.org/maven2 timed out and maven reported that this repository had been blacklisted.

And that's it. I grepped through all the files in ~/.m2, lots of POM files mention the given URL, but nothing looks like blacklisting. So basically the tool error'ed out and I don't have any clue how to fix it. Plus, there is of course no documentation about this "feature" at all. Every attempt to download a plugin or a dependency fails by now.
