What version have you used before?

The temporary "workaround" is to remove configuration filters from project configurations. Then the Groovy script evaluation will be skipped.

BTW, evaluation failures should not break the jobs loading...

I don't know which version exactly was running before, sorry.

The workaround works (somewhat) – I manually edited the config.xml file and commented out the <combinationFilter> line, which makes the project appear again after a jenkins restart or "reload config from disk".

However, the filter was there intentionally of course, i.e. we need to filter there otherwise other things would break, so a permanent fix for this would be very welcome.

Could you share the failing script?

I'm getting the same error. I didn't lose all my jobs. Can't parse out why I lost the ones I did and kept others. But heres the log output

zgallagher: Your script is likely referencing a class that's not available in the new Matrix Project plugin's class loader by it's fully qualified name (e.g. hudson.model.Hudson). But it'd be best if you would share your script(s) – or a simplified variant that also shows the problem – to facilitate further analysis.

I've tried with a Groovy script (in Combination Filter) that contains only "true" (the simplest possible expression). Same error and stacktrace.

Fixing in 1.1.

I've upgraded from 1.556 to 1.568, and am still seeing this exact exception.
I'm not seeing JENKINS-22863 in http://jenkins-ci.org/changelog - is it in a build already?

I have updated both the plugin (used v1.2) and core.
I've updated all relevant plugins after upgrading the core, exactly because of this change.
Still the issue appeared.

@ykaul and did you double-check that you are really running 1.2 in /pluginManager/installed? And that you are really seeing the same problem as is reported here and not something else? Best to install Support Core and attach a diagnostic bundle so others can see what you are really running and the original error in the log.

I've installed from fresh Jenkins 1.569, from RPM. I have the matrix plugin 1.2 installed as well as https://wiki.jenkins-ci.org/display/JENKINS/matrix+combinations+plugin v1.06.
When creating the simples matrix job, the exception occurs.
Here's my job:

• multi-configuration job
• parameterized:
• bool parameter (dummy, just to have a parameter)
• matrix combinations filter: name: FILTER
• Configuration Matrix:
• User Defined Axis: name: ax1 values: axA axB
• User Defined Axis: name: ax2 values: axC axD

That's it. No steps, no nodes, no git, nothing.
When I go to execute it:

@ykaul sounds like a separate bug while I filed as JENKINS-23561.

Every plugin using /lib/project/matrix tag causes the same problem.

@ikedam I grepped @jenkinsci sources for references to this tag. I found only the usage from matrix-combinations-parameter, filed as JENKINS-23561.

Fixed matrix-combinations-parameter-plugin in 1.0.7.
It will be available in a day.

marix-combinations-parameter-plugin no longer depends on /lib/project/matrix tag. (It is anyway required to fix JENKINS-23030).

Looks good on my setup: had 1.556, upgraded the plugin first, then to 1.570, and all seems to be working.
Thanks!
