It'd be nice to have a checkbox option for the [ArtifactDeployer] plugin to cause the build to fail if the artifacts specified in the "Files to deploy" field do not exist. The current behavior of the plugin is to succeed even if there are zero artifacts matching the specified file/wildcard expression.
