Is there any update on this please

Thanks

Kohsuke made a change which is included in the current release which may fix the parsing of the changelog, although I'm looking to change the whole way the changelog is parsed in the current iteration which will fix your issue. I'm not going to be able to start work on this for a couple of weeks, but will link changes back to this defect so they are visible.

I'm having the same problem, I believe.

I'm currently running Jenkins 1.478, with the 2.5 CVS plugin.

Shane - I believe you're actually encountering a different issue, but need you to confirm something: does the current job have any successfully completed (non cancelled) jobs?

I don't believe that any of the jobs had been cancelled. I just stumbled across JENKINS-14711 and tried the workaround for changing the date separator in the changeDate field to use '-' instead of '/'. That made the changelogs visible.

Hi Michael,
Unfortunately I still get this error with Jenkins v1.492 and CVS Plugin v2.8:

Let me know if/how I can provide more info.

Fred,

I suspect you have an invalid exclude pattern configure for one of your repositories. The NPE is thrown because we're failing to try and compile a pattern and are then trying to log the error using the listener for a launcher, despite not being passed a launcher by Jenkins (a side affect of not using a workspace for polling). I'll fix the NPE by changing the exception block to use the provided listener, rather than try and use a launcher's listener. I can then give you a snapshot if you want to try and track down the underlying exception that we're currently failing to log?

Thanks,
Michael

Hi Michael,
There was indeed a problem with the exclude pattern.
Let me know when the snapshot is ready, then I can test it.

Regards,
Fred
