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 $transition = Get-JiraIssue -Issue TEST-01 | Select-Object -ExpandProperty Transition | ? {$_.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 [PSJira.Issue] Issue (can also be provided as a String) [PSJira.Transition] Transition to perform (can also be provided as an int ID) .OUTPUTS This function does not provide output. #> [CmdletBinding()] param( [Parameter(Mandatory = $true, Position = 0, ValueFromPipeline = $true, ValueFromPipelineByPropertyName = $true)] [Alias('Key')] [Object] $Issue, [Parameter(Mandatory = $true, Position = 1)] [Object] $Transition, # Credentials to use to connect to Jira [Parameter(Mandatory = $false)] [System.Management.Automation.PSCredential] $Credential ) begin { # We can't validate pipeline input here, since pipeline input doesn't exist in the Begin block. } process { Write-Debug "[Invoke-JiraIssueTransition] Obtaining a reference to Jira issue [$Issue]" $issueObj = Get-JiraIssue -InputObject $Issue -Credential $jCred if (-not $issueObj) { Write-Debug "[Invoke-JiraIssueTransition] No Jira issues were found for parameter [$Issue].
