jql function haslinks not found

The "haslinks" function is not a built-in function in JQL (Jira Query Language). However, you can create a custom JQL function using the ScriptRunner add-on for Jira.

Here's an example of how to create a custom JQL function called "haslinks" using ScriptRunner:

1. Install ScriptRunner add-on for Jira if you haven't already.
2. Navigate to ScriptRunner > Script Fragments in Jira.
3. Click on "Add" to create a new script fragment.
4. Select "JQL Function" as the fragment type.
5. Enter "haslinks" as the name for the function.
6. Enter the following script in the "Code" section:

import com.atlassian.jira.component.ComponentAccessor

def issueManager = ComponentAccessor.getIssueManager()

def issuesWithLinks = issueManager.getIssueObjects(issue.id).any { issueLinkType ->
  issueLinkType.getOutwardLinks().size() > 0 || issueLinkType.getInwardLinks().size() > 0
}

return issuesWithLinks

7. Save the script fragment.
8. Run a JQL query using the "haslinks" function. For example:

project = MYPROJECT AND haslinks()

This will return all issues in the "MYPROJECT" project that have links.
