Description

When we have a pipeline which is started like this:

def mainHandler

node{

    checkout scm

    mainHandler = load "deployment/Jenkinsfile"

}

mainHandler.runIntegration(this)

and "deployment/Jenkinsfile" looking like:



#!groovy



package com.xxx.groovy.integration



def runIntegration(def configuration) {

    node{

....

    }

}

When we restart the Jenkins Master, resuming is not possible:

```

Raw content of original issue

When we have a pipeline which is started like this:




def mainHandler

node{

    checkout scm

    mainHandler = load "deployment/Jenkinsfile"

}

mainHandler.runIntegration(this)






and "deployment/Jenkinsfile" looking like:


 


#!groovy



package com.xxx.groovy.integration



def runIntegration(def configuration) {

    node{

        ....

    }

}






When we restart the Jenkins Master, resuming is not possible:

Research direction

Start in the workflow-cps-plugin entry points shown in the trace, especially CpsFlowExecution.loadProgramAsync and onLoad, and reproduce the failure with the pipeline using load "deployment/Jenkinsfile" and its package declaration. Done means a restarted Jenkins Master can load the build state and resume the pipeline without the Script1 ClassNotFoundException.
