The current code assumes that the term "viewvc" is part of the URL.

private static final String CHANGE_SET_FORMAT = "viewvc/?view=rev&root=%s&revision=%d";
private static final String DIFF_FORMAT = "viewvc/%s?root=%s&r1=%d&r2=%d&diff_format=h";
private static final String FILE_FORMAT = "viewvc/%s?root=%s&view=markup";

As we do not have influence on the ViewVC installation (different team which takes care of Subversion + ViewVC), the /viewvc/ folder is not part of our URLs:

https://svn.company.com/cgi-bin/viewvc.cgi/REPONAME/
https://svn.company.com/cgi-bin2/viewvc.cgi/REPONAME/

With the current project config parameters:

• URL: https://svn.company.com/cgi-bin/viewvc.cgi/
• Repository: REPONAME

The plugin will create the following URL which do not work:

• https://svn.company.com/cgi-bin/viewvc.cgi/viewvc/REPONAME/
• https://svn.company.com/cgi-bin2/viewvc.cgi/viewvc/REPONAME/
