Ruby Plugin causes jobs to fail to load



    • Similar Issues:


      Adding an action to a build using a Ruby plugin causes the build to fail to load when Jenkins is restarted.

      The error looks like this:

      SEVERE: Failed Loading job cool

      The bug was originally mentioned in IRC on April 11th by dragonkh_: http://echelog.com/logs/browse/jenkins/1334095200

      Relevant parts of the IRC conversattion:

      <cowboyd> dragonkh_: do you get an exception on startup?
      <dragonkh_> cowboyd - it happens when I start up jenkins
      <dragonkh_> cowboyd - http://pastie.org/3768530
      <dragonkh_> cowboyd - thats the exception I get on starting up jenkins - the job fails to load
      <dragonkh_> is it in the ruby-runtime somewhere?
      <cowboyd> can you send me the xml for the job?
      <cowboyd> It's the persistence that is getting confused.
      <dragonkh_> cowboyd - isnt this the config? http://pastie.org/3768541
      <dragonkh_> cowboyd - check my code here: https://github.com/masterthought/jenkins-cucumber-jvm-reports-plugin
      <cowboyd> dragonkh: can I see the xml for the build?
      <dragonkh_> cowboyd - http://pastie.org/3768765
      <cowboyd> yes, that's it. kohsuke: ^^ any idea why jruby-xstream would be handing the ruby object and not the jruby proxy?

      <dragonkh> cowboyd - got any idea where I can have a look ?
      <cowboyd> yes, it's in the deserialization code. https://github.com/jenkinsci/jruby-xstream
      <dragonkh> is that part of the main jenkins release?
      <cowboyd> all ruby plugins depend on it
      <dragonkh> or is it part of the ruby-runtime ?
      <cowboyd> jenkins.rb/java-runtime depends on it
