How to delete directories with path/names too long for normal delete

Problem

Windows seems to have a length limit on file names when trying to delete, though it won't prevent those files from being created. Our build process creates a number of temporary files (many build off of a WSDL) that run afoul of this limit. Our ant script is somehow able to delete them when doing a clean, but sometimes I need to delete the workarea directory (where all the temp files go) without actually doing a full clean from ant. This is the same errors this question, but the answers there don't really work for me as I'm dealing with a directory, not a file, and I don't always know what specific files or subdirectories are causing the problem. And I'm trying to avoid any manual process (other than triggering a single command) to actually delete them. If I try deleting the directory from Explorer I get the error Trying in powershell gives the following error: Does anyone know of any tools or easy ways to get around this delete error without having to manually find the problem files …
