JQL expression editor

JQL expression features

The JQL expression editor has the ability to:

  • Check for syntax errors in the Nunjucks code

  • Colorize keywords, comments, variables and so on

The editor also provides advanced features, such as find and replace, that are available through keyboard shortcuts.

Lookup user

By 29 April 2019, Atlassian will remove personal data from the API that is used to identify users, such as username and userKey, and instead, use the Atlassian account ID (accountId). These are the impacts on JMWE:

  • If the JQL in your existing "Link issue to current issue" post-functions are using the username or the userkey they need to be replaced with the accountId.

  • If you are adding/modifying the JQL in the Link issues to current issue post-function you should not anymore specify the username or userkey but only the accountId. For example, JQL return the issues assigned to a specific user

However, the accountId is not obvious in Jira. You can use this Lookup user feature in the Nunjucks editor to find the accountId of a user. To know the accountId of a user:

  1. Click on the Lookup user button

  2. Select the user from Search for user

  3. Click on Insert accountId

JQL expression tester

The JQL expression tester lets you test your expression against any issue. You can quickly test and debug your expression and make changes without having to actually trigger the transition and/or look at the JMWE logs to see the result.

Using the JQL expression tester

After writing your JQL expression in the editor, click on Test JQL expression. A window opens, asking you to input an issue to run the JQL expression against. The issue variable used in your annotations will point to this issue.

The transition variable will not reflect transition information during testing.

Testing your JQL expression

After selecting an issue against which the JQL expression should be tested, click on Test. The following information will be displayed. This information can be used for debugging.

  1. Message: Success/error message based on the test result.

  2. Parsed JQL query: The parsed JQL query

  3. Issues: The result of the JQL query which is an array of issues.

Example:

Test a JQL expression that fetches issues in a project that are assigned to the current user.

  • Add the Link issues to current issue post-function to a transition.

  • In the JQL editor, write the following lines of code:

    project = TEST and assignee = {{currentUser.accountId}}

     

  • Select maximum number of issues in Max. Issues.

  • Click on Test JQL expression

  • Type the Issue key of an issue.

  • Click on Test.

  • The following result is displayed:

 

Debugging your JQL expression

If you encounter an error during testing or your JQL expression doesn't seem to fetch expected results, you will need to debug your expression. The information displayed in the result panel aids in debugging the expression.

In the above example if you provided "==" instead of "=":

project = TEST and reporter == {{currentUser.accountId}}

  • Test the JQL expression, as explained above. The following result will be displayed.

  • Identify the problem, from the Message that displayed an error that, there is an error in the JQL query

  • Correct the problem, by modifying the expression

    project = TEST and reporter = {{currentUser.accountId}}

     

  • Retest the expression, by clicking on Test again and verify the result in the template test panel.
