I ran the deploy goal just now, because these artifacts were not previously uploaded. I ran this against my saved RC-9 build directory (the one that was approved). To my surprise, it rebuilt the jars - I'm not sure why... and deployed those. It may have been related to the fact that I had switched to Maven 3 for some experimenting, and that was the Maven in place when I first ran the deploy goal, but that failed without deploying anything. But it may have altered something... I then switched back to Maven 2.2.1 and the deploy proceeded without error.
