Scenario
You have Threat Match Condition set to Open Issue Only and this is resulting in JEMH creating a new issue instead of commenting on the related Issue but you would like to extract a field from the related issue to then be added to the new issue.
Implementation
This script will find and gather a Custom Field value from the related issue and will then add the value from the Custom Field to the new issue that is being created.
if (relatedIssue === null) //Checks if the email is commenting on a issue.
{
var allReferences = jemhUtils.getReferencedMessageIds().toString(); //Gathers all of the References from the email to check if a Issue Message-Id is found
var pattern = Java.type("java.util.regex.Pattern").compile("JIRA\.([0-9]+)\."); //Regex to extract only the IssueId from the Message-Id
var matcher = pattern.matcher(allReferences);
if(matcher.find()) //Runs if a match is found
{
var group = matcher.group(1); //Gathers the first Regex match
var matchedIssue = issueManager.getAllIssueKeys(group).toString().replace("[", "").replace("]", ""); //Searchs for the issue with the id
var fieldObject = customFieldManager.getCustomFieldObjectByName("example"); //Creates a Custom Field Object for the relevant Custom Field, "example" needs to be changed
var fieldValue = issueManager.getIssueObject(matchedIssue).getCustomFieldValue(fieldObject); //Checks for a value within the issue that matched the Id
if (fieldValue !== null) // Checks if there is a value set, If there is then add this value to new issue
{
print("value was found on the related issue: "+ matchedIssue);
resultMap.put("example", fieldValue); //Sets value on the new issue, "example" needs to be changed to the field name
}
}
}
