how  to copy value  from assignee value  to group picker

[Alexey Matveev]

You can not copy assignee value to a group picker, because assignee is of the ApplicationUser type and group picker is of the Group type.

any other way have to auto populate the user's group value to group picker

[Alexey Matveev]

Do you want to populate a group of an assignee to a group picker? And what if an assignee belongs to multiple groups?

That is how you populate a group picker

import com.atlassian.jira.component.ComponentAccessor

def customFieldManager = ComponentAccessor.getCustomFieldManager()
def groupManager = ComponentAccessor.getGroupManager()

def multiGroupCf = customFieldManager.getCustomFieldObjectByName("multigrouppicker")
def singleGroupCf = customFieldManager.getCustomFieldObjectByName("GroupPicker")

def group = groupManager.getGroup("jira-developers")

issue.setCustomFieldValue(multiGroupCf, [group])
issue.setCustomFieldValue(singleGroupCf, [group])

And you can get a group of an assignee like this

def groups = ComponentAccessor.getGroupManager().getGroupNamesForUser(issue.getAssignee().getName())

how to run this script in jira because i am new to jira.

[Alexey Matveev]

You need a plugin. The scripts, which I provided, can be run by ScriptRunner. You can also use Power Scripts add-on. But there will be a different script.  The script will be easier.
