Hi Guys, I'm getting an exception after running my own DSL task 'P4Groovy':
The extension is here <https://github.com/jenkinsci/p4-plugin/tree/master/src/main/java/org/jenkinsci/plugins/p4/groovy>, in 'GetP4' I extend Builder and implement SimpleBuildStep to execute the task and then create the step by extending 'Step' in 'GetP4Step' (that bit of code has been updated from 'AbstractStepImpl'). However, the exception remains the same regardless of my recent updates. The build step runs and I can see the output in the log, however on close of the workflow it throw the exception below... In Jenkins 1.642.3 I get no NPE, however with 2.32 I see the NPE? If I mark my use of TaskListener listener as transient then no exception? However no logs for my DSL task :-( Any pointers would be greatly appreciated. Kind regards, Paul Apr 11, 2017 5:30:01 PM org.jenkinsci.plugins.workflow.cps.CpsThreadGroup saveProgramIfPossible WARNING: program state save failed java.io.IOException: Failed to persist
