Support for PSResourceGet

[johlju]

Pull Request

Pull Request (PR) description

Added

• Support for PSResourceGet (beta release). If the modules PSResourceGet can be bootstrapped they will be used. If PSResourceGet cannot be bootstrapped then it will revert to using PowerShellGet v2.2.5. If the user requests or configures to use ModuleFast then that will override both PSResourceGet and PowerShellGet. The method PSResourceGet can be enabled in the configuration file Resolve-Dependency.psd1. It is also possible to use PSResourceGet by adding the parameter UsePSResourceGet to the build.ps1, e.g. ./build.ps1 -Tasks noop -ResolveDependency -UsePSResourceGet.
• When using PSResourceGet to resolve dependencies it also possible to use PowerShellGet v2.9.0 (previous CompatPowerShellGet). To use the compatibility module it can be enabled in the configuration file Resolve-Dependency.psd1. It is also possible to use it by adding the parameter UsePowerShellGetCompatibilityModule to the build.ps1, e.g. ./build.ps1 -Tasks noop -ResolveDependency -UsePSResourceGet -UsePowerShellGetCompatibilityModule. The 2.9.0-preview has since then been unlisted, the compatibility module will now be released as PowerShellGet v3.0.0.

Changed

• PowerShell Team will release the PSResourceGet compatibility module (previously known as CompatPowerShellGet) as PowerShellGet v2.9.0 (or higher). The resolve dependency script, when PowerShellGet is used, will use MaximumVersion set to 2.8.999 to make sure the expected PowerShellGet version is installed, today that it is v2.2.5. The 2.9.0-preview has since then been unlisted, the compatibility module will now be released as PowerShellGet v3.0.0.
