refs #1212 fixes version conflict
Prevent NoSuchMethodError in fetch_summary. Call "get_recent_builds" instead of "open".
Required length option for truncate.
Since find_hudson_job can return REXML::ParseException, exception bundling should be required. (E.g. Jenkins returns non xml result because authentication failed with invalid password or credential.)
Escape error message.
Merge branch 'redmine_hudson/redmine2.x' into redmine2.x
