The plugin works perfectly, but there is an annoying cosmetic bug.
If you select one of the following option in the job configuration:

• Trigger only if build is stable
• Trigger even if the build is unstable
• Trigger even if the build fails
  the config is properly stored into the config.xml of the job. But, if you reload/reopen the job configuration UI in jenkins, the first option "Trigger only if build is stable" is always selected, no matter what is really selected in the config.xml of the job.
