Since we are about to deploy River jars to the ASF Jar Repository, I'd like to make sure that as a project, we understand what needs to happen. Please review this document: http://www.apache.org/dev/publishing-maven-artifacts.html
Since we are not a Maven project, and we do not use Ivy, I wrote a Groovy script that uses the Maven deploy plugin (http://maven.apache.org/plugins/maven-deploy-plugin/deploy-file-mojo.html) to deploy River artifacts. If you want to be able to deploy to the ASF repository you must configure Maven according to the guidelines in the referenced document. Aside from the various configuration guidelines, of interest is the "Common Procedures" section as well. I've tested the deployment script, a staging repository does get created with the artifacts. I have also "dropped" the repository, since we are not yet ready to release 2.2.1. Regards Dennis
