function Get-JiraGroupMember { <# .Synopsis Returns members of a given group in JIRA .DESCRIPTION This function returns members of a provided group in JIRA. .EXAMPLE Get-JiraGroupmember testGroup This example returns all members of the JIRA group testGroup. .EXAMPLE Get-JiraGroup 'Developers' | Get-JiraGroupMember This example illustrates the use of the pipeline to return members of the Developers group in JIRA. .INPUTS [PSJira.Group] The group to query for members .OUTPUTS [PSJira.User[]] Members of the provided group .NOTES By default, this will return all active users who are members of the given group. For large groups, this can take quite some time. To limit the number of group members returned, use the MaxResults parameter. You can also combine this with the StartIndex parameter to "page" through results. This function does not return inactive users.
