Maven 2 plugin that can be used to access various operations on a given URL using a supported maven wagon. Supports recursive upload, download, and list directory content functionality. The Kuali version of this plugin exists, because the Maven version ignores the filePermissions tag from settings.xml when uploading artifacts to a repository.

There is a newer version: 1.0.5
