I'm a bit of a NuGet newbie and have come from the Maven world.

Recently I've been tasked with updating the third party licence information for our projects. Working with the Maven projects I've been able to use the license:download-licenses plugin to get the licence information.

What I'm wondering is if there is a way to get this information using Nuget? Preferably by using the command line interface so I can automate it at a CI build level. To remove it from the large manual pre build step.

EDIT:

Since I wasn't able to find any utilities to do this I put together the LegSec command line utility.

• licensing
• nuget

As far as I am aware there is nothing currently available to get the license information directly from the command line as part of a CI build. You would need to create an application to open the .nupkg zip file, extract the license url from the .nuspec file and download the license from this url.

Alternatively you could use the package manager console window inside Visual Studio and with a bit of PowerShell download the license files.

A simple example that gets the license file for all packages in a project is shown below. This would need to be extended to get all the projects in the solution which you should be able to do with the Get-Project cmdlet. This would still require someone to run the script to download the licenses.

$wc = New-Object System.Net.WebClient
Get-Package -ProjectName YourProject | ForEach-Object {
    $wc.DownloadFile($_.LicenseUrl, 'd:\licenses\' + $_.Id + ".html")
}

I managed to get the licence information with the following command:

@(@(Get-Project -All | ForEach-Object {
    Get-Package -ProjectName $.ProjectName
}) | Select Id -Unique ) | ForEach-Object {
    $pkg = $_
    $pkgId = $_.Id
    if ($pkgId -notlike 'microsoft*') {
        $url = Open-PackagePage $pkgId -License -WhatIf -PassThru
        Write-Host "$pkgId $url"
    }
}
