function Set-JiraIssueLabel { <# .Synopsis Modifies labels on an existing JIRA issue .DESCRIPTION This function modifies labels on an existing JIRA issue. There are four supported operations on labels: * Add: appends additional labels to the labels that an issue already has * Remove: Removes labels from an issue's current labels * Set: erases the existing labels on the issue and replaces them with the provided values * Clear: removes all labels from the issue .EXAMPLE Set-JiraIssueLabel -Issue TEST-01 -Set 'fixed' This example replaces all existing labels on issue TEST-01 with one label, "fixed". .EXAMPLE $jql = 'created >= -7d AND reporter in (joeSmith)' Get-JiraIssue -Query $jql | Set-JiraIssueLabel -Add 'enhancement' This issue adds the "enhancement" label to all issues matching the JQL set in the $jql variable - in this case, all issues created by user joeSmith in the last 7 days. .INPUTS [JiraPS.Issue[]] The JIRA issue that should be modified .OUTPUTS If the -PassThru parameter is provided, this function will provide a reference to the JIRA issue modified. Otherwise, this function does not provide output. #> [CmdletBinding(DefaultParameterSetName = 'ReplaceLabels')] param( # Issue key or JiraPS.Issue object returned from Get-JiraIssue [Parameter(Mandatory = $true, Position = 0, ValueFromPipeline = $true, ValueFromPipelineByPropertyName = $true)] [Alias('Key')] [Object[]] $Issue, [Parameter(ParameterSetName = 'ReplaceLabels', Mandatory = $true)] [Alias('Label','Replace')] [String[]] $Set, # Existing labels to be added [Parameter(ParameterSetName = 'ModifyLabels')] [String[]] $Add, # Existing labels to be removed [Parameter(ParameterSetName = 'ModifyLabels')] [String[]] $Remove, # Remove all labels [Parameter(ParameterSetName = 'ClearLabels')] [Switch] $Clear, # Credentials to use to connect to Jira [Parameter(Mandatory = $false)] [System.Management.Automation.PSCredential] $Credential, [Switch] $PassThru ) begin { Write-Debug "[Set-JiraIssueLabel] Reading server from config file" $server = Get-JiraConfigServer -ConfigFile $ConfigFile -ErrorAction Stop } process { foreach ($i in $Issue) { Write-Debug "[Set-JiraIssueLabel] Obtaining reference to issue" $issueObj = Get-JiraIssue -InputObject $i -Credential $Credential if ($issueObj) { $currentLabels = @($issueObj.labels) $url = $issueObj.RestURL $isDirty = $true # As of JIRA 6.4, the Add and Remove verbs in the REST API for # updating issues do not support arrays of parameters - you # need to pass a single label to add or remove per API call. # Instead, we'll do some fancy footwork with the existing # issue object and use the Set verb for everything, so we only # have to make one call to JIRA. if ($Clear) { Write-Debug "[Set-JiraIssueLabel] Clearing all labels" $newLabels = @() } elseif ($PSCmdlet.ParameterSetName -eq 'ReplaceLabels') { Write-Debug "[Set-JiraIssueLabel] Set parameter was used; existing labels will be overwritten" $newLabels = $Set } elseif ($currentLabels -eq $null -or $currentLabels.Count -eq 0) { Write-Debug "[Set-JiraIssueLabel] Issue currently has no labels" if ($Add) { Write-Debug "[Set-JiraIssueLabel] Setting labels to Add parameter" $newLabels = $Add } else { Write-Debug "[Set-JiraIssueLabel] No labels were specified to be added; nothing to do" $isDirty = $false } } else { Write-Debug "[Set-JiraIssueLabel] Calculating new labels" # If $Add is not provided (null), this can end up with an # extra $null being added to the array, so we need to # account for that in the Where-Object as well as the # Remove parameter. $newLabels = $currentLabels + $Add | Where-Object -FilterScript {$_ -ne $null -and $Remove -notcontains $_} } if ($isDirty) { Write-Debug "[Set-JiraIssueLabel] New labels for the issue: [$($newLabels -join ',')]" $props = @{ 'update' = @{ 'labels' = @( @{ 'set' = @($newLabels); } ); } } Write-Debug "[Set-JiraIssueLabel] Converting labels to JSON" $json = ConvertTo-Json -InputObject $props -Depth 4 Write-Debug "[Set-JiraIssueLabel] JSON:`n$json" Write-Debug "[Set-JiraIssueLabel] Preparing for blastoff!" # Should return no results $result = Invoke-JiraMethod -Method Put -URI $url -Body $json -Credential $Credential } else { Write-Debug "[Set-JiraIssueLabel] No changes are necessary." } if ($PassThru) { Write-Debug "[Set-JiraIssue] PassThru was specified.
