Issue Security in Jira sub-tasks and the Script Runner plugin

I’ve been trying to do some advanced JIRA configuration recently, with mixed success.

The requirement was to have issues in a project which could be viewed only by a specific user (not necessarily the assignee).

I discovered that “Issue Security Schemes” can have levels which allow access based on a “User Custom Field Value”. Fantastic. I added a custom field, let’s call it “Employee”, and added it to an Issue Security Level. Applied to the project and bingo, users can only see issues where they have been entered into the “Employee” field.

Too easy. I added a subtask to an issue where I was the employee. No error message, but no subtask appeared either.

My understanding was that you could not set issue security on subtasks, because they inherit the issue security of the parent. I assumed the intention of this was that if you could see an issue, you should be able to see its children. But no – they specifically inherit the issue security setting from the parent, rather than its visibility – as confirmed in Atlassian Answers. So because the sub-task does not have an “Employee” field, I can’t see it. Bother.

Of course, I could use a workflow post-function so that when subtasks are created, the employee field is set to that of the parent. But what if the value is changed in the parent? It’s a nuisance to have to change all the sub-tasks too.

Time to investigate the Script Runner plugin.

Here’s the code for my Scripted field, which gets the value of the Employee field in the parent issue.

import com.atlassian.jira.ComponentManager
import com.atlassian.jira.issue.CustomFieldManager
import com.atlassian.jira.issue.Issue
import com.atlassian.jira.issue.fields.CustomField

def componentManager = ComponentManager.getInstance()
def parentIssue = issue.getParentObject();
CustomFieldManager cfManager = ComponentManager.getInstance().getCustomFieldManager()

CustomField customField = cfManager.getCustomFieldObject(99999)

It is almost too easy. I think it may be the answer to some of the other requests I’ve had for custom fields in JIRA, but unfortunately it doesn’t solve this problem. The calculated value appears perfectly on the page when viewing a sub-task. But, when I go to the “Issue Security Level” and click in the “User Custom Field Value” drop down, it doesn’t appear! It’s configured with the “User Picker” Searcher and template, so I don’t think there’s much more I can do.

Back to the drawing board…


Writing a maven 3 plugin in groovy

I thought I’d document this, as we found it a bit confusing to get going, and the documentation is fairly sparse.

We wanted to knock up a quick maven plugin which would parse some XML files, and output some HTML. Great, a chance to do some groovy foo! Parsing and writing XML with groovy is so easy, we thought we’d try writing the plugin in groovy. Once compiled, groovy is just java, so Maven should not care what the plugin is written in.

First, DON’T follow these instructions: They only work in Maven 2.

For reference, the error message when compiling the plugin:

Failed to execute goal org.codehaus.mojo.groovy:groovy-maven-plugin:1.0-beta-3:generateStubs (default) on project firstgroovy-maven-plugin: Execution default of goal org.codehaus.mojo.groovy:groovy-maven-plugin:1.0-beta-3:generateStubs failed: An API incompatibility was encountered while executing org.codehaus.mojo.groovy:groovy-maven-plugin:1.0-beta-3:generateStubs: java.lang.NoSuchMethodError: org.codehaus.plexus.PlexusContainer.hasChildContainer(Ljava/lang/String;)Z

The correct approach for maven 3 is documented here:

It still doesn’t work straight away. If you follow the guidelines and create the pom and mojo as in this page (specifiying 1.5 for the gmaven versions), the mojo appears to install but then when you execute it from another project, you get the following error:

 org.sonatype.guice.bean.reflect.Logs$JULSink warn
WARNING: Error injecting: sample.plugin.GreetingMojo
java.lang.NoClassDefFoundError: Lorg/codehaus/groovy/reflection/ClassInfo;

The answer is on this page:

We need to add the following to the gmaven-plugin configuration:


I’ve attached a zip containing a working mojo and a test project: groovy-maven-plugin.tar.gz. Run mvn install on the first to install it in your local repository, then mvn compile onthe second to see it execute.
