How to convert an Attachment Object to a File Object using Scriptrunner in Jira v10

[Chris Solgat]

We have upgraded our Jira instance to version 10.3.5.

Previously, we used the com.atlassian.jira.util.AttachmentUtils.getAttachmentFile(Attachment attachment) method to retrieve a File object for a given attachment, which we would then use to copy the file to a local directory for secondary processing.

In Jira 10, AttachmentUtils.getAttachmentFile() has been removed, so we replaced it with ComponentAccessor.getAttachmentManager().getAttachment(attachment.id). Based on the migration recommendations, we are now using com.atlassian.jira.issue.AttachmentManager to retrieve Attachment objects. However, we are unable to determine how to convert attachment object to file object and are receiving the below error:

ERROR org.codehaus.groovy.runtime.typehandling.GroovyCastException: Cannot cast object 'com.atlassian.jira.issue.attachment.Attachment@********' with class 'com.atlassian.jira.issue.attachment.Attachment' to class 'java.io.File'

Or even more simple, does anyone know how to find the filepath of the Attachment object in the Jira 10 api's?

Hello Chris,

I am using the following code to create a list of Files from the attachments of an issue:

package console

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.config.util.JiraHome
import com.atlassian.jira.issue.attachment.Attachment
import com.atlassian.jira.issue.Issue
import com.atlassian.jira.issue.IssueManager

IssueManager issueManager = ComponentAccessor.issueManager
Issue thisIssue = issueManager.getIssueObject('ABC-1')

return getAttachments(thisIssue)



List<File> getAttachments(Issue issue) {
    List<File> files = []

    List<Attachment> attachments = ComponentAccessor.attachmentManager.getAttachments(issue)
    String bucket = (10000L * Math.ceil(issue.number / 10000D).toInteger()).toString()
    JiraHome jiraHome = ComponentAccessor.getComponent(JiraHome)
    String path = "${jiraHome.homePath}/data/attachments/${issue.projectObject.key}/${bucket}/${issue.key}"

    attachments.each { attachment ->
        if (attachment.mimetype.toString().startsWith("image")) {
            String thisFile = "${path}/${attachment.id}"

            File file = new File(thisFile)
            files.add(file)
        }
    }

    return files
}

I hope this helps. :-)
