Replicate Jira's Native Email Handler

This script is invoked by the SIL mail handler to process an incoming email in the same manner as JIRA's default "Create issue or add comment" mail handling option.

To use this script, you will have to modify the destination projectKey and issueType for your purposes.

IncomingEmail mail = getIncomingEmail();

string issueKey = matchText(mail.subject, "[A-Z][A-Z]+-[0-9]+"); // find an issue key in the subject
if(isNull(issueKey)) {
    // if no issue key found, create a new issue
    string [] fields = {};
    fields += {"reporter", getUserByEmail(mail.from[0]).key};
    fields += {"assignee", getUserByEmail(mail.to[0]).key};

    string newIssue = createIssue(
      "PROJ", //projectKey
      "", //parentIssueKey
      "Task", //issueType
      mail.subject, //summary
      "Medium", //priority
      mail.body, //description
      {}, //components
      "", //dueDate
      "", //estimate
      "", //security_level
      fields //custom_fields_mappings
    );
    attachAllFilesFromEmail(newIssue);
    %newIssue%.watchers = getUserKeysFromEmails(mail.cc);
} else {
    // if issue key found in subject, add a comment
    addComment(issueKey, currentUserKey(), mail.body);
}
