groovy.lang.MissingFieldException: No such field: binding for class: WorkflowScript
Issue Type: Improvement Improvement
Assignee: Unassigned
Components: pipeline
Created: 2017/Mar/14 11:15 PM
Priority: Critical Critical
Reporter: Sorin Sbarnea

I tried to print all pipeline variables in a loop and I got an exception from groovy.

// put this inside stage block:

for (k in this.binding.variables) {
  try {
    v = this.binding.variables[k]
    println "$k = $v";
    }
  catch(Exception ex) {
    println("Catching the exception: ${ex}");
    }	
}

Re: groovy.lang.MissingFieldException: No such field: binding for class: WorkflowScript

I'll defer to Kohsuke Kawaguchi or Jesse Glick, but I don't think binding is supposed to be available at the user level here.

So fwiw, I reproduced this with the original without being in a stage. And it works if you go with this.getBinding() instead of this.binding. Why that is...I'm still not exactly sure. So I'm going to leave this open to remind me to dig into that at some point, but it's not exactly a priority.

Re: groovy.lang.MissingFieldException: No such field: binding for class: WorkflowScript

I have noticed that getBinding() only returns the variable steps that point to the DSL. Looking at https://github.com/jenkinsci/workflow-cps-plugin/blob/workflow-cps-2.67/src/main/java/org/jenkinsci/plugins/workflow/cps/DSL.java#L131-L200, you could get all sort of things from that object (would need approve a lot of signatures through Script security though...):

println "\nfunctions\n***********"
println this.steps.functions.collect { k,v -> v.getFunctionName()}

println "\nstepClassNames\n***********"
println this.steps.stepClassNames.collect { k,v -> v.getFunctionName()}

println "\nunreportedAmbiguousFunctions\n***********"
println this.steps.unreportedAmbiguousFunctions.collect { k,v -> v.getFunctionName() }

println "\nallGlobalVariables\n***********"
println org.jenkinsci.plugins.workflow.cps.GlobalVariable.forRun(currentBuild.rawBuild).collect { var -> var.getName() }

println "\nallSymbols\n***********"
println getAllSymbols().collectMany { symbol -> org.jenkinsci.plugins.structs.SymbolLookup.getSymbolValue(symbol) }

@NonCPS
def getAllSymbols() {
    return org.jvnet.hudson.annotation_indexer.Index.list(
            org.jenkinsci.Symbol.class,
            jenkins.model.Jenkins.get().pluginManager.uberClassLoader,
            Class.class)
}
