Install-SPSolution : This solution contains no resources scoped for a Web application and cannot be deployed to a particular Web application

Question

I have a powershell script that deploys about 12 web parts. They have all been created in the manner through visual studio 2010 and are being deployed to sharepoint 2010.

I am getting the following error when running Install-SPSolution for one of my web parts: Install-SPSolution : This solution contains no resources scoped for a Web appli cation and cannot be deployed to a particular Web application.

Can someone help me debug this? Every other Install-SPSolution command uses -AllWebApplications, and I do not want to specify the web application directly using -URL. Here is the command that is breaking (this is the same command used to successfully deploy all 11 other web parts):

Install-SPSolution –Identity PortalSelector.wsp -AllWebApplications -GACDeployment

Thanks.

Answer 1

If the solution has no web application resources it is considered a global solution and does not actually need to target an web applications. Remove the -AllWebApplicaitons and this global solution will be deployed globally to the farm and will be available to all web applicaitons.

Answer 2

Or try checking the ContainsWebApplicationResource property on the solution object itself

$solutions = Get-SPSolution
foreach ($solution in $solutions)
{    
    if ($solution.ContainsWebApplicationResource)
    {
        $solution | Install-SPSolution -AllWebApplications -Confirm:$false
    }
    else
    {
        $solution | Install-SPSolution -Confirm:$false
    }
}

Answer 3

I think question was how to deploy to a particular webapplication which is best practice also..

answer is

Install-SPSolution -Identity "MySPSolution.wsp" –WebApplication "http://localhost" –GACDeployment
