Question

We are using hudson version 2.0.0.
Few days back after restarting hudson, i found that some of the jobs were missing.
Found that its due to the following NPE.

Dec 9, 2011 11:39:34 AM hudson.model.Hudson$5 onTaskFailed

Upgrading to 2.1.2 didnt help. I removed all the plugins and re-installed, but in vain.
Has anybody else faced this?

Thanks,

Answer 1

OK I found the problem.

To fix this issue, I had to add the line that contains <publishers/> to each config.xml file in projects that failed to load (towards the end of XML file):

  </builders>
  <buildWrappers/>
  <publishers/>
</project>

Somehow without this, Hudson/Jenkins barfs and hides in the corner crying.
