How to create issues in jira programmatically inside a listener?

[Shagufta Gurmukhdas]

I want to programmatically create issues and assign, inside a listener, for example, a VersionCreateEvent. How to do that? Will that be possible with the REST API?

Here code exmple for Java API. Try to adopt it for listener

package IssueCreation

import com.atlassian.jira.bc.issue.IssueService
import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.Issue
import com.atlassian.jira.issue.IssueInputParameters
import com.atlassian.jira.issue.index.IssueIndexManager
import com.atlassian.jira.user.ApplicationUser
import com.atlassian.jira.user.util.UserManager
import com.atlassian.jira.util.ErrorCollection

/**

//Issue issue = null;

IssueService issueService = ComponentAccessor.getIssueService();
IssueInputParameters inputParameters = issueService.newIssueInputParameters();

UserManager userManager = ComponentAccessor.getUserManager();

inputParameters
        .setProjectId(issue.getProjectId())
        .setIssueTypeId("11504")
        .setReporterId(ComponentAccessor.getJiraAuthenticationContext().getUser().getName())
        .setSummary(issue.getSummary())
        .setAssigneeId(userManager.getUserByKey(issue.getAssigneeId()).getName())

ApplicationUser curUser = ComponentAccessor.getJiraAuthenticationContext().getUser();

IssueService.CreateValidationResult createValidationResult = issueService.validateCreate(curUser, inputParameters)

if(!createValidationResult.isValid()){
    ErrorCollection errorCollection = createValidationResult.getErrorCollection();
    return errorCollection.toString()
}
else{
    IssueService.IssueResult createResult = issueService.create(curUser, createValidationResult)
    IssueIndexManager issueIndexManager = ComponentAccessor.getIssueIndexManager();
    issueIndexManager.reIndex(createResult.getIssue())
}

 @Vasiliy Zverev , Writing the same inside an event listener would work, right?

[Vasiliy Zverev]

@Shagufta Gurmukhdas, yes it should. 

Note that all values are set into inputParameters object.
