Complex JQL Function

[Akhil Jain]

I have requirement to find certain linked issues of a issue in particular project or all of JIRA based on criteria.

The requirement is too find all the tickets which have due date later than parent linked issue 

For Eg. 
              Issue Ticket(MM/dd/yyyy)                                          Linked Issues

       ABCDEF-15(Due Date- 09/01/2018) ---> KLMNOP-254 (07/31/2018)
                                                                 ---> KLMNOP-380 (06/30/2018)
                                                                 ---> KLMNOP-410 (09/30/2018)
                                                                 ---> KLMNOP-415 (09/30/2018)
                                                                 ---> TUVWXY-12484 (06/30/2018)
                                                                 ---> KLMNOP-385 (06/30/2018)
                                                                 ---> KLMNOP-271 (06/30/2018)
                                                                 ---> KLMNOP-273 (06/30/2018)
                                                                 ---> KLMNOP-336 (12/31/2021)

Final Result

 Issue Ticket                                               Linked Issues(dates after link due date)

ABCDEF-15(Due Date- 09/01/2018)         ---> KLMNOP-410 (09/30/2018)
                                                                  ---> KLMNOP-415 (09/30/2018)
                                                                  ---> KLMNOP-336 (12/31/2021)

I want the linked issue for ABCDEF-15, this is a specific type of ticket.

The example provided Example JQL Function is too simple and does not explain the JQL API.

Here is my sample code

import java.util.LinkedList;
import java.util.List;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import com.atlassian.crowd.embedded.api.User;
import com.atlassian.jira.JiraDataType;

import com.atlassian.jira.jql.query.QueryCreationContext;
import com.atlassian.jira.plugin.jql.function.AbstractJqlFunction;

import com.atlassian.plugin.spring.scanner.annotation.imports.ComponentImport;
import com.atlassian.query.clause.TerminalClause;
import com.atlassian.query.operand.FunctionOperand;

/**

 */
@Scanned
public class AkhilTestJqlFunction extends AbstractJqlFunction 
{
 private static final Logger log = LoggerFactory.getLogger(AkhilTestJqlFunction.class);
 
 @ComponentImport
 private final IssueLinkManager issueLinkManager;
 
 @ComponentImport
 private final IssueManager issueManager;
 
 @ComponentImport
 private final CustomFieldManager customFieldManager;
 
 public AkhilTestJqlFunction(IssueLinkManager issueLinkManager, IssueManager issueManager,
 CustomFieldManager customFieldManager) {
 super();
 log.warn("warn- AkhilTestJqlFunction constructor got called");
 log.debug("debug- AkhilTestJqlFunction constructor got called");
 log.trace("trace- AkhilTestJqlFunction constructor got called");
 this.issueLinkManager = issueLinkManager;
 this.issueManager = issueManager;
 this.customFieldManager = customFieldManager;
 }

public MessageSet validate(User searcher, FunctionOperand operand, TerminalClause terminalClause)
 {
 return validateNumberOfArgs(operand, 1);
 }

public List<QueryLiteral> getValues(QueryCreationContext queryCreationContext, FunctionOperand operand, TerminalClause terminalClause)
 {
 log.warn("warn- get values got called");
 log.debug("debug- get values got called");
 log.trace("trace- get values got called");
 final List<QueryLiteral> literals = new LinkedList<QueryLiteral>();
 /*final List<UserHistoryItem> projects = userProjectHistoryManager.getProjectHistoryWithoutPermissionChecks(queryCreationContext.getApplicationUser());

for (final UserHistoryItem userHistoryItem : projects) {
 final String value = userHistoryItem.getEntityId();

try {
 literals.add(new QueryLiteral(operand, Long.parseLong(value)));
 } catch (NumberFormatException e) {
 log.warn(String.format("User history returned a non numeric project IS '%s'.", value));
 }
 }*/
 
 return null;
 }

public int getMinimumNumberOfExpectedArguments()
 {
 return 0;
 }

public JiraDataType getDataType()
 {
 return JiraDataTypes.ISSUE;
 }

public MessageSet validate(ApplicationUser arg0, FunctionOperand operand, TerminalClause arg2) {
 return validateNumberOfArgs(operand, 0); 
 }
 
 
 
}

The above code is still in progress code.

Please help by providing solution and pointing me in right direction.

@Akhil Jain 

Were you able to complete it ? Could you share how you acheived it ?

[Ignacio Pulgar]

Hi Akhil,

Do you have ScriptRunner plugin available on your Jira instance? This one would avoid the necessity for coding, as it provides many convenient JQL functions.

By the way, speaking of Issue Links, we better speak of outward and inward links, rather than parent-child relationship, unless you are specifically referring to:

• a standard issue which is the parent of a sub-task
• rarely, an Epic which is a parent of a standard issue. When using the word 'parent' to refer to an Epic, it is usually refereed to as a 'parent epic' instead.

Sample outward/inward link descriptions are:

• blocks/is blocked by
• causes/is caused by
• relates to/relates to

Note those are not parent/child relationships, specially obvious in the 'relates to' case.

You can find the issue link types here:

<Jira URL>/secure/admin/ViewLinkTypes!default.jspa

If you provide us with more information about the outward/inward descriptions you would like to use, we might helps you further.

Regards.

[Akhil Jain]

@Ignacio Pulgar Yes you are right, these are inward and outward links.
Yes I have ScriptRunner plugin.

These are mostly blocks/is blocked by links. 1-2 of them are relates to/relates.

Q.1 How can we return result from Scriptrunner plugin?

[Ignacio Pulgar]

Hi Akhil,

Provided that dateCompare compares just dates from the very same issue, groovy code is required.

Maybe @Alexey Matveev _Appfire_ can help you further, as he is a distinguished Champion with widely proven scripting expertise.

[Akhil Jain]

Thanks @Ignacio Pulgar .
Waiting for response from @Alexey Matveev _Appfire_

Just for the record, please, kindly note that Alexey might be willing to help you, solely based on his own decision, as he does not have any obligations to solve, or even to answer to this question.

Community Champions contribute here just for fun.

So, we are in fact asking him for a favor :)

Best regards

Yes Thanks for all the help.

@Alexey Matveev _Appfire_ Please help with the problem.

Hello,

You would need to override getQuery function in Scriptrunner 

 @Override
 Query getQuery(QueryCreationContext queryCreationContext, FunctionOperand operand, TerminalClause terminalClause) 
 

Inside the function you need to select all issues which you want to check (you should limit the number of the issues by your jql query or your function will take too much time to execute):

ApplicationUser user = ComponentAccessor.getJiraAuthenticationContext().getLoggedInUser() 
def booleanQuery = new BooleanQuery() 
issueResults = searchService.search(user, subQuery, PagerFilter.getUnlimitedFilter())
List<Issue> issues = issueResults.getIssues()
for (Issue curIssue in issues) {
}

Then inside the cycle you should check every issue for the condition you need and if it satisfies your condition then you can add the issue to booleanQuery

booleanQuery.add(new TermQuery(new Term("issue_id", curIssue.id as String)), BooleanClause.Occur.SHOULD)
 }

Then return booleanQuery

return booleanQuery;

[Akhil Jain]

@Alexey Matveev _Appfire_ Thanks for the help. It really cleared my doubt.

I have few more questions
Q.1 How would i override getQuery in ScriptRunner?
Q.2 In the code you shared, what exactly is subQuery and searchService?

issueResults = searchService.search(user, subQuery, PagerFilter.getUnlimitedFilter())

 Do I need to integrate the code you shared in Custom JQL Function?

[Alexey Matveev]

1. Kindly have a look at the following tutorial. It is how you overide it:

https://scriptrunner.adaptavist.com/latest/jira/custom-jql-functions.html

2. You can write something like this

subQuery = "poject = TEST"

it is a usual JQL query.

[Akhil Jain]

will calling the JQL function automatically initialize subQuery?

[Alexey Matveev]

No, you need to define it in your script like

def subQuery = "poject = TEST"

[Akhil Jain]

I want sub query to come from user search, if there is any..instead of me manually adding in JQL function

[Alexey Matveev]

You can pass a JQL string as a parameter and then use it. If you pass it as the first parameter you can get it by 

operand.args[0]

How to concatenate for queries where 
project ="xyz" and issuetype="Defect" and customJqlFunction


will it internally manage all the issues from concentated query
Will this work fine??
