Since the old repository is not available any longer (https://repo.grails.org/grails/core) my grails wrapper stopped working. The URL has changed to https://repo.grails.org/artifactory/core See https://github.com/grails/grails-core/issues/11825 Unfortunately this older URL is hardcoded in Start.java: https://github.com/grails/grails-wrapper/blob/master/starter/src/main/java/grails/init/Start.java#L22
