Static type checking- The variable [jiraHelper] /issue is undeclared- script editor

[Mouna Hammoudi]

I am using a condition in my script in the REST endpoint and I am receiving the following errors. JiraHelper and Issue are not recognized.

Anyone knows what the problem is and what needs to be fixed?

Here is the code:

 package CreateMultipleSubtasks



import org.apache.log4j.Logger
 import com.atlassian.jira.plugin.webfragment.model.JiraHelper
 import com.atlassian.jira.component.ComponentAccessor




def log1 = Logger.getLogger("atlassian-jira.log")

log1.warn("MOUNA BEFORE")
Configuration_CreateMultipleSubtasks conf = new Configuration_CreateMultipleSubtasks()
def subTaskCreatorHashMap= conf.getSubTaskCreatorHashMap()


String projectKey = subTaskCreatorHashMap["projectKey"];
String issueTypeName = subTaskCreatorHashMap["issueTypeName"];

log.warn("MOUNA PROJECT KEY "+ projectKey+" issuetypename "+issueTypeName)
def val=jiraHelper.project?.key==projectKey  &&  issue.issueType.name==issueTypeName

return val
