function Invoke-JiraIssueTransition { <# .Synopsis Performs an issue transition on a JIRA issue, changing its status .DESCRIPTION This function performs an issue transition on a JIRA issue. Transitions are defined in JIRA through workflows, and allow the issue to move from one status to the next. For example, the "Start Progress" transition typically moves an issue from an Open status to an "In Progress" status. To identify the transitions that an issue can perform, use Get-JiraIssue and check the Transition property of the issue object returned. Attempting to perform a transition that does not apply to the issue (for example, trying to "start progress" on an issue in progress) will result in an exception. .EXAMPLE Invoke-JiraIssueTransition -Issue TEST-01 -Transition 11 Invokes transition ID 11 on issue TEST-01. .EXAMPLE Invoke-JiraIssueTransition -Issue TEST-01 -Transition 11 -Comment 'Transition comment' Invokes transition ID 11 on issue TEST-01 with a comment. Requires the comment field to be configured visible for transition. .EXAMPLE Invoke-JiraIssueTransition -Issue TEST-01 -Transition 11 -Assignee 'joe.bloggs' Invokes transition ID 11 on issue TEST-01 and assigns to user 'Joe Blogs'. Requires the assignee field to be configured as visible for transition. .EXAMPLE $transitionFields = @{'customfield_12345' = 'example'} Invoke-JiraIssueTransition -Issue TEST-01 -Transition 11 -Fields $transitionFields Invokes transition ID 11 on issue TEST-01 and configures a custom field value. Requires fields to be configured as visible for transition. .EXAMPLE $transition = Get-JiraIssue -Issue TEST-01 | Select-Object -ExpandProperty Transition | ? {$_.ResultStatus.Name -eq 'In Progress'} Invoke-JiraIssueTransition -Issue TEST-01 -Transition $transition This example identifies the correct transition based on the result status of "In Progress," and invokes that transition on issue TEST-01. .INPUTS [JiraPS.Issue] Issue (can also be provided as a String) [JiraPS.Transition] Transition to perform (can also be provided as an int ID) .OUTPUTS This function does not provide output. #> [CmdletBinding()] param( # The Issue Object or ID to transition.
