<# .SYNOPSIS Installs a package from a Nuget repository like Nuget.org using nuget.exe .DESCRIPTION Installs a package from a Nuget repository like Nuget.org using nuget.exe Relevant Dependency metadata: Name: The name of the package Version: Used to identify existing installs meeting this criteria. Defaults to 'latest' Source: Source Uri for Nuget. Defaults to https://www.nuget.org/api/v2/ Target: Required path to save this module. No Default Example: To install PSDeploy to C:\temp\PSDeploy, I would specify C:\temp .PARAMETER Force If specified and Target already exists, remove existing item before saving .PARAMETER PSDependAction Test, or Install the package. Defaults to Install Test: Return true or false on whether the dependency is in place Install: Install the dependency .EXAMPLE @{ 'Newtonsoft.Json' = @{ DependencyType = 'Nuget' Target = 'C:\Temp' Version = '12.0.2' } } # Install Newtonsoft.Json via Nuget.org, to C:\temp, at version 12.0.2 .EXAMPLE @{ 'MyCompany.Models' = @{ DependencyType = 'Nuget' Source = 'https://nuget.int.feed/' Target = 'C:\Temp' } } # Install the latest version of MyCompany.Models on an internal nuget feed, to C:\temp .EXAMPLE @{ PSDependOptions = @{ DependencyType = 'Nuget' Target = ".\Staging" } 'Portable.BouncyCastle' = @{ Version = 'latest' Parameters = @{ Name = 'BouncyCastle.Crypto' } } 'MimeKit' = 'latest' 'Newtonsoft.Json' = 'latest' } # Installs the list of Nuget packages from Nuget.org using the Global PSDependOptions to limit repetition. Packages will be downloaded to the Staging directory in the current working directory.
