    Description

      Hudson actually builds the working .war artifact but fails on some useless post-build step with the following in the console output:

      [HUDSON] Archiving disabled - not archiving /opt/m/tomcat6/webapps/hudson/jobs/Network-Partners-Main/workspace/netw-reports.pom

      This is critical because this way we can't see which builds failed which actually succeeded.

      Please let me know if other info is needed.

          Moving to "other" component since the bug seems to be in the screenshot plugin.
