I have two lines script based on examples:
def pain = getCustomFieldValue("Pain if not delivered") def gain = getCustomFieldValue("Gain if delivered")
which returns me an error:
Script function failed on issue: TP-1, actionId: 11, file: <inline script> groovy.lang.MissingMethodException: No signature of method: org.codehaus.groovy.jsr223.GroovyScriptEngineImpl.getCustomFieldValue() is applicable for argument types: (java.lang.String) values: [Pain if not delivered] at Script21.run(Script21.groovy:1)
How can I solve that?
I'm not sure where you've got the examples from, but I doubt they say getCustomFieldValue(<string>)
You need to pass those calls a customfield object, not a random string - it doesn't know what to do with strings. For example:
def cf = customFieldManager.getCustomFieldObject ("Gain if delivered")
def gain = getCustomFieldValue(cf)
(My notes actually say issue.getCustomFieldValue, but I've got a feeling groovy may not need it if you're in a post-function as it assumes you mean "current issue")
I tried another way:
import com.atlassian.jira.ComponentManager; import com.atlassian.jira.issue.CustomFieldManager; def painFieldId = "customfield_11401"; def gainFieldId = "customfield_11402"; ComponentManager componentManager = ComponentManager.getInstance() CustomFieldManager customFieldManager = componentManager.getCustomFieldManager() def gainCustomField = customFieldManager.getCustomFieldObject(gainFieldId); def painCustomField = customFieldManager.getCustomFieldObject(painFieldId);
Now I'm reaching: No signature of method: com.atlassian.jira.ComponentManager.getCustomFieldManager() is applicable for argument types: () values: 
Hi - you should use "ComponentAccessor" to get JIRA managed component according to the latest document:
def customFieldManager = ComponentAccessor.getCustomFieldManager()
please check the doc for more detail: https://docs.atlassian.com/jira/latest/com/atlassian/jira/component/ComponentAccessor.html
The suggestion is based on this link: https://docs.atlassian.com/jira/latest/com/atlassian/jira/ComponentManager.html
