WorkflowScript.with in Jenkins

问题

I have a class in a jenkins shared library that stores the instance of a WorkflowScript class from a jenkins pipeline script as shown below.

def myTools = new my.org.MyTools(this)

the constructore of MyTools just stores the instance of WorkflowScript like this...

MyTools(script){
    this.script = script
}

then I have a method that tries to use groovy's .with on script but fails...

myMethod(){
    script.with{
        node{
            echo "I want to be able to use pipeline syntax here"
            sh 'echo "without using script. in front of each command"'
        }
    }
}

But when I run this i get the following error...

hudson.remoting.ProxyException: groovy.lang.MissingMethodException: No signature of method: org.jenkinsci.plugins.workflow.cps.CpsClosure2.node() is applicable for argument types: (org.jenkinsci.plugins.workflow.cps.CpsClosure2) values: [org.jenkinsci.plugins.workflow.cps.CpsClosure2@855f14e]

I would have expected the inside of the script.with closure to have access to all of the same stuff as script., but it looks like it only has access to methods of java.lang.Object. Is it possible to get the script.with closure to function with the same context of script.?

回答1:

for groovy closure possible to specify strategy which the closure uses to resolve methods and properties

there are options: DELEGATE_FIRST, DELEGATE_ONLY, OWNER_FIRST (default), OWNER_ONLY, TO_SELF

i think the pipeline script has a special strategy, and in your class there is a default one.
