Hi Team,

Currently we are facing critical issues on using Jenkins File or Pipeline to overwrite the Custom Job parameters.

Pipeline or Jenkins file is not allowing to use the 
def build= Thread.currentThread()?.executable
Getting below error
org.jenkinsci.plugins.scriptsecurity.sandbox.RejectedAccessException: unclassified field java.lang.Thread executable
I tried inline pipeline also enabling and disabling the Use Groovy Sandbox option once its enable getting the above RejectedAccessException Error if I disable I am getting the below error
groovy.lang.MissingPropertyException: No such property: executable for class: java.lang.Thread
 

Could you please let me know how we can update the Custom Job parameter on workflow and this needs to be used in other stages of the pipeline. Since our deployment scripts will read the Parameter vale from UNIX. Initially the value will be null based on some conditions we will update the parameter. 

We tried the below option also.

def newbuildparms =[:]
newbuildparms.put('$Param1', 'TestOverwrite')

setBuildParameters(newbuildparms)

def setBuildParameters(map) {
def npl = new ArrayList<StringParameterValue>()
for (e in map) {
npl.add(new StringParameterValue(e.key.toString(), e.value.toString()))
}
def newPa = null
newPa = new ParametersAction(npl)

build.actions.add(newPa)
}

This throws below error
java.io.NotSerializableException: java.util.LinkedHashMap$Entry
 

We tried all the options nothing worked us.

We are not able to achieve this and its always going as null when read the parameter from outside of jenkins, we are not able to update the current job parameters in workflow.

Jenkins version 2.19.1
