I use http://wiki.hudson-ci.org/display/HUDSON/Log+Parser+Plugin You can use regular expressions to classify log entries as info, warning or error. You can configure job to fail if there are warnings or errors present in log.
This may not be exactly what you are looking for, since plugin parses console output and not specific log file created by build. I could not find a way to store parsing rules to version control. Parsing rules are part of Jenkins configuration. -- You received this message because you are subscribed to the Google Groups "Jenkins Users" group.
