IMPORTANT Between version 1.0 and 1.1 (snapshot build from 20040130), the id of the utilities plugin was changed from avalon-plugin to avalon-util-plugin. Please check that your maven plugin directory DOES NOT contain the old avalon-plugin (if it does please delete the avalon-plugin-1.0.jar file and the avalon-plugin-1.0 directory). To use the avalon-util-plugin please ensure that the jar file is copies to you maven/plugins directory.
