How to construct link to an attachment

[Hana Kučerová]

Hello,

I'm trying to create a comment in issue, which contains link to some specific attachment from another issue (let's assume it has id = 10001).

Below is the code, which I use to get the attachment and construct the link.

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.config.properties.APKeys
import com.atlassian.jira.issue.AttachmentManager
import com.atlassian.jira.issue.attachment.Attachment

ApplicationProperties applicationProperties = ComponentAccessor.getApplicationProperties()
AttachmentManager attachmentManager = ComponentAccessor.getAttachmentManager()

String baseUrl = applicationProperties.getString(APKeys.JIRA_BASEURL)
Long attachmentId = 10001

Attachment attachment = attachmentManager.getAttachment(attachmentId)
String attachmentUrl = "$baseUrl/secure/attachment/${attachment.id}/${URLEncoder.encode(attachment.filename, 'UTF-8')}"

Everything works fine for me, but I've been wondering, if there is a better way to create the attachment's url (variable attachmentUrl). This is the best solution, I've been able to find, but it seems to me, that there should be some method, to which I provide attachment id and which returns constructed link. Am I missing something?

Thank you very much!
