JIRA ScriptRunner mail handler error

[Lev Ryvkin]

Hello!

I'm trying to create custom ScriptRunner Mail Handler to create issue with attachments from incoming mail.

Here is the code

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.config.util.JiraHome
import com.atlassian.jira.service.services.file.FileService
import com.atlassian.jira.service.util.ServiceUtils
import com.atlassian.jira.service.util.handler.MessageUserProcessor
import com.atlassian.jira.user.ApplicationUser
import com.atlassian.jira.user.util.UserManager
import com.atlassian.mail.MailUtils
import org.apache.commons.io.FileUtils

def userManager = ComponentAccessor.getComponent(UserManager)
def projectManager = ComponentAccessor.getProjectManager()
def issueFactory = ComponentAccessor.getIssueFactory()
def messageUserProcessor = ComponentAccessor.getComponent(MessageUserProcessor)
JiraHome jiraHome = ComponentAccessor.getComponent(JiraHome)

def subject = message.getSubject() as String
def issue = ServiceUtils.findIssueObjectInString(subject)
if (issue) {
return
}

ApplicationUser user = userManager.getUserByName("admin")
ApplicationUser defaultReporter = userManager.getUserByName("admin")
def project = projectManager.getProjectObjByKey("HL")

def issueObject = issueFactory.getIssue()
issueObject.setProjectObject(project)
issueObject.setSummary(subject)
issueObject.setDescription(MailUtils.getBody(message))
issueObject.setIssueTypeId(project.issueTypes.find { it.name == "Bug" }.id)
issueObject.setReporter(defaultReporter)
issue = messageHandlerContext.createIssue(user, issueObject)

def attachments = MailUtils.getAttachments(message)

attachments.each { MailUtils.Attachment attachment ->
def destination = new File(jiraHome.home, FileService.MAIL_DIR).getCanonicalFile()
def file = FileUtils.getFile(destination, attachment.filename) as File
FileUtils.writeByteArrayToFile(file, attachment.contents)
messageHandlerContext.createAttachment(file, attachment.filename, attachment.contentType, user, issue)
}

The problem is: issue is created successfully, but there is no attachment added and message file was not deleted after processing. Run Now test button returns a strange error:

Other:

C:\Program Files\Atlassian\Application Data\JIRA\import\mail\__utf_8_B_Rlc6IEVYVF0g0J3QvtCy0YvQuSDQvtGC0LLQtdGCINC90LAg0LDQvdC60LU___ ___utf_8_B_0YLRgyAi0JPQvtGA0Y_Rh9Cw0Y8g0LvQuNC90LjRjyI___.eml (The filename, directory name, or volume label syntax is incorrect)

I am exporting .eml from our exchange mailbox to \import\mail\ directory. Every message has a default name template as "message_0.eml", "message_1.eml" etc.

I've found out myself. The problem was in this block:

def attachments = MailUtils.getAttachments(message)

attachments.each { MailUtils.Attachment attachment ->
def destination = new File(jiraHome.home, FileService.MAIL_DIR).getCanonicalFile()
def file = FileUtils.getFile(destination, attachment.filename) as File
FileUtils.writeByteArrayToFile(file, attachment.contents)
messageHandlerContext.createAttachment(file, attachment.filename, attachment.contentType, user, issue)
}

 My eml file was containing .msg file as attachment. This attachment was exported from eml file and was forcefully converted to eml from msg. It also had "[] :" symbols in its name which were lost during base64 encoding-decoding process.

The problem was resolved by using static name string "Attachment.eml" instead of attachment.filename variable
