In order to determine what to use for <archetype_version>, go to the Hobson web console's Plugins tab and click the "Show all plugins" checkbox. Look for the plugin named "Hobson Hub Core" and note what's in the version column (e.g. 0.1.3). This should be used for the archetype version in the command aboveinstall directory and find the "bundle" folder. One of the files in that folder will be a "hobson-hub-core-x.y.z.jar". The corresponding archetype version will be x.y.0. For example, if the file is hobson-hub-core-0.8.1.jar, then the archetype version will be 0.8.0.
