Hello SharePoint Fam,
I am still kind of lost on deploying/removing sharepoint featuers/solutions from the farm fully and want to try get understanding once and for all on totally cleaning or deploying a feautre/solution to try and keep clean environment and get rid of server
dependcies error
Below are my steps I follow but not sure if this is correct:
Add/Deploy Solution:
Add wsp file to C:\
1) Add-SPSolution -LiteralPath <SolutionPath>(C:\)
2) Install-SPSolution -identity <SOlutionName> -webapplication <URLNAME>
3) Confirm if solution deployed Get-SPSolution <SolutionName>
Remove a solution
Deactivate solution/feature from sites (Disable-SPFeature -identity "MyCustom" -URL http://somesite)
1) Uninstall-SPSolution -Identity <SolutionName> -WebApplication <URLName>
2) Remove-SPSolution -Identity <SolutionName>
Thanks n advance

Hi,
Here is the complete PowerShell script.
$solutionName="solutionname.wsp"
$featureName="featurename"
$SolutionPath="C:\wsp\"+$solutionName
if($args[0] -eq 'DEV') {
$webAppName="http://url"
elseif ($args[0] -eq 'QA') {
$webAppName="http://url"
elseif ($args[0] -eq 'PROD') {
$webAppName="http://url"
else {
Write-Host "$(Get-Date -Format o) Environment not specified - please pass appropriate environment to deploy -"
exit
Function WaitForJobToFinish([string]$SolutionFileName)
$JobName = "*solution-deployment*$SolutionFileName*"
$job = Get-SPTimerJob | ?{ $_.Name -like $JobName }
if ($job -eq $null)
Write-Host 'Timer job not found'
else
$JobFullName = $job.Name
Write-Host -NoNewLine "Waiting to finish job $JobFullName"
while ((Get-SPTimerJob $JobFullName) -ne $null)
Write-Host -NoNewLine .
Start-Sleep -Seconds 2
Write-Host "Finished waiting for job.."
$powershellSnapin = "Microsoft.Sharepoint.Powershell"
if ((Get-PSSnapin -Name $powershellSnapin -ErrorAction SilentlyContinue) -eq $null )
Write-Host "--------------------------------- Adding sharpoint powershell snapin if not existing-------------------------"
Add-PsSnapin $powershellSnapin
if($DeployWebURL -eq '')
Write-Host "$(Get-Date -Format o) Incorrect Environment specified - please pass 'DEV/QA/PROD' -"
exit
Write-Host 'Going to disable feature ' $featureName
disable-spfeature -identity $featureName -confirm:$false -url $webAppName
Write-Host 'Going to uninstall feature ' $featureName
uninstall-spfeature -identity $featureName -confirm:$false -force
Write-Host 'Going to uninstall solution '$solutionName
Uninstall-SPSolution -identity $solutionName -confirm:$false
Write-Host 'Waiting for job to finish'
WaitForJobToFinish
Write-Host 'Going to remove solution'
Remove-SPSolution –identity $solutionName -confirm:$false
Write-Host 'Going to add solution '$SolutionPath
Add-SPSolution $SolutionPath
Write-Host 'Going to install solution to web application '$solutionName
Install-SPSolution –identity $solutionName –GACDeployment
do
Write-Host “.” -NoNewline -ForeGroundColor Green;
Start-Sleep -Seconds 5;
try
write-host 'Verifying if the solution installation is valid'
$testsolution = Get-SPSolution -Identity $solutionName
catch
}while(!$testsolution);
Write-Host 'Going to enable Feature ' $featureName
Enable-spfeature -identity $featureName -confirm:$false -url $webAppName
Write-Host 'Enabled Feature' $featureName
Remove-PsSnapin Microsoft.SharePoint.PowerShell
Apart from this, there might be some situations deployment will not be successful due to some issues.  In that scenario, you have to either go the Central Admin to kill the Job or use the PowerShell script to kill the job.  And then start fresh
deployment.
