Dynamic class loading from apps API

Edited

Good day,

I try to prepare groovy script to realize logic before export with Better Excel Exporter.

I need to read value from project custom field (projectrak/profields app) and with scriptrunner I make it this way

import com.deiser.jira.profields.api.field.FieldService
import com.deiser.jira.profields.api.field.list.ListField
import com.deiser.jira.profields.api.value.ValueService

@WithPlugin("com.deiser.jira.profields")

def valueService = ComponentAccessor.getOSGiComponentInstanceOfType(ValueService.class)
def fieldService = ComponentAccessor.getOSGiComponentInstanceOfType(FieldService.class)

ListField field = fieldService.get("Included in the week reports").get(0)
def fieldValue = valueService.getValue(project, field)

But groovy in Better Excel Exporter dont have this features of scriptrunner and I try to make it with dynamic class loading this way

in class constructor I make loading of classes

valueServiceClass=ComponentAccessor.pluginAccessor.classLoader.loadClass("com.deiser.jira.profields.api.field.FieldService")
fieldServiceClass=ComponentAccessor.pluginAccessor.classLoader.loadClass("com.deiser.jira.profields.api.value.ValueService")
listFieldClass=ComponentAccessor.pluginAccessor.classLoader.loadClass("com.deiser.jira.profields.api.field.list.ListField")
valueService=ComponentAccessor.getOSGiComponentInstanceOfType(valueServiceClass) fieldService=ComponentAccessor.getOSGiComponentInstanceOfType(fieldServiceClass) listField=ComponentAccessor.getOSGiComponentInstanceOfType(listFieldClass)

But with log I see that listFieldClass= interface com.deiser.jira.profields.api.field.list.ListField

and listField=null (looks that is not right)
and then in function I want to make read of field value like this

def field = this.listField.newInstance()
field = this.fieldService.get("Included in the week reports").get(0)
def fieldValue = this.valueService.getValue(project, field)

But script doesn't go through line with def field = this.listField.newInstance()

 

In logs I don't see exact groovy error message, only messages of fail render from Better Excel Export app. And I don't have experience yet with dynamic class loading so maybe I just failed with code logic
