How to copy all versions from a multi-version picker custom field to Fix Versions

[עדי וקנין]

Hi,

I want to copy FixVersion/s field to custom field Fix Version (Single version picker).

I assisted by this post and rewrite the script mentioned in here:  https://community.atlassian.com/t5/Jira-questions/Copy-Affects-Version-and-Fix-Version-values-to-new-Version/qaq-p/127058  (Jeremy code).

when i running this code on the script console in script runner i get the next error:

2018-04-17 12:53:56,645 WARN [common.UserScriptEndpoint]: Script console script failed: java.lang.NullPointerException: Cannot invoke method getId() on null object at Script12.run(Script12.groovy:21

what am I missing here?

This is the code:

import com.atlassian.jira.ComponentManager;
import com.atlassian.jira.component.ComponentAccessor;
import com.atlassian.jira.issue.Issue;
import com.atlassian.jira.project.version.Version;
import com.atlassian.jira.issue.IssueManager;
import com.atlassian.jira.issue.CustomFieldManager;
import com.atlassian.jira.issue.fields.CustomField;
import com.atlassian.jira.event.type.EventDispatchOption;
import com.atlassian.jira.project.Project;
import com.atlassian.jira.project.ProjectManager;
import java.util.ArrayList;
import java.util.Collection;

IssueManager issueManager = ComponentAccessor.getIssueManager();
ProjectManager projectManager = ComponentAccessor.getProjectManager();
CustomFieldManager customFieldManager = ComponentAccessor.getCustomFieldManager();
CustomField nvcf = customFieldManager.getCustomFieldObjectByName("Fix Version"); // Fix Version Custom Field

Project project = projectManager.getProjectByCurrentKey("PROC");
Collection<Long> projectIssueIds = issueManager.getIssueIdsForProject(project.getId());

projectIssueIds.each {
Issue issue = issueManager.getIssueObject(it);
Object fixVersions = issue.getFixVersions();
Object newFieldVersions = issue.getCustomFieldValue(nvcf);
issue.setCustomFieldValue(nvcf,fixVersions);
issueManager.updateIssue(ComponentAccessor.getJiraAuthenticationContext().getLoggedInUser(), issue, EventDispatchOption.ISSUE_UPDATED, false);

}

The system field 'Fix Version/s' is multi-version.

Try to change your custom field to be Version Picker (multiple versions).
