Installing tools from NuGet

Cake provides different ways to install tool executables available as NuGet packages as part of a build.

Installing tools via pre-processor directive

The #tool pre-processor directive for Cake .NET Tool can be used to automatically download a tool and install it in the tools folder.

The following example downloads the xunit.runner.console package as part of executing your build script:

#tool "nuget:?package=xunit.runner.console&version=2.4.1"

Installing tools with InstallTool

Cake Frosting provides a InstallTool method to download a tool and install it:

The following example downloads the xunit.runner.console package as part of executing your build script:

public class Program : IFrostingStartup
{
    public static int Main(string[] args)
    {
        // Create and run the host.
        return
            new CakeHost()
                .InstallTool(new Uri("nuget:?package=xunit.runner.console&version=2.4.1"))
                .Run(args);
    }
}

Installing tools from other providers

Out of the box NuGet and .NET Tools (since Cake 1.1) is supported as provider for Pre-processor directive and InstallTool. More providers are available through Modules.

Using tools from disk

To use a tool that's not available via NuGet or if you prefer to store the tool locally, Cakes tool resolution conventions can be used to resolve the path to the tool and call it through a process alias:

Task("Install-XUnit")
    .Does(()=> {
    FilePath nugetPath = Context.Tools.Resolve("nuget.exe");
    StartProcess(nugetPath, new ProcessSettings {
        Arguments = new ProcessArgumentBuilder()
            .Append("install")
            .Append("xunit.runner.console")
        });
});
