But when you open this "SVN" repository with either the SVN Repository View in eclipse (or with the SVN command line in Ubuntu) you get the error:
Error validating location: "org.apache.subversion.javahl.ClientException"
Detected a cycle while processing the operation
svn: Redirect cycle detected for URL 'http://svn.apache.org/viewvc/commons/sandbox/id'
Clearly, this is not the SVN repository for the Apache Commons Sandbox. You get the same error for other elements in the Apache Sandbox such as Convert
So the question remains: Is there a JAR file (e.g. commons-id.jar) to download or is there a URL to a properly formed SVN repository from which one can do an anonymous checkout of the org.apache.commons.id.uuid package?
