I saw a post on lucene java-dev where someone was wanting an update to our snapshots for the sandbox.
Until we have continuous integration, any committer who has done the additional setup (http://uima.apache.org/one-time-release-setup.html) can deploy snapshots by using the mvn deploy command. (You don't need the gpg signing setup for deploying, just the pw mechanisms for accessing the repo servers). I'm running that now for the add-ons projects. -Marshall
