.NET C# Java Javascript Exception

This blogpost is a follow up to these Cake (C# Make) related blogpost:

Scenario

Let’s say we have this project structure. The “Config”, “Result” and “Engine” projects contains a corresponding .nuspec, like this:

<?xml version="1.0"?>
<package >
 <metadata>
 <id>Sloader.Config</id>
 <version>$version$</version>
 <title>Sloader.Config</title>
 <authors>Code Inside Team</authors>
 <owners>Code Inside Team</owners>
 <licenseUrl>https://github.com/Code-Inside/Sloader/blob/master/LICENSE</licenseUrl>
 <projectUrl>https://github.com/Code-Inside/Sloader</projectUrl>
 <requireLicenseAcceptance>false</requireLicenseAcceptance>
 <description>Sloader Config</description>
 <releaseNotes>
 ## Version 0.1 ##
 Init
 </releaseNotes>
 <copyright>Copyright 2017</copyright>
 <tags>Sloader</tags>
 <dependencies />
 </metadata>
</package>

Nothing fancy - pretty normal NuGet stuff, but be aware of the “$version$” variable. This variable is called a “replacement-token”. When the NuGet package is created and it detects such a replacement-token, it will search for the AssemblyVersion (or other replacement-token sources).

Versioning in NuGet:

I’m not a NuGet expert, but you should also versioning your assembly info, otherwise some systems may have trouble to update your dll. The version inside the package can be different from the actual assembly version, but you should manage booth or use this replacement-token-mechanic.

Goal

The goal is to create a NuGet package for each target project with Cake.

build.cake

The usage in Cake is pretty much the same as with the normal nuget.exe pack command The sample only shows the actual cake target - see the older blogposts for a more complete example:

Task("BuildPackages")
 .IsDependentOn("Restore-NuGet-Packages")
	.IsDependentOn("RunTests")
 .Does(() =>
{
 var nuGetPackSettings = new NuGetPackSettings
	{
		OutputDirectory = rootAbsoluteDir + @"\artifacts\",
		IncludeReferencedProjects = true,
		Properties = new Dictionary<string, string>
		{
			{ "Configuration", "Release" }
		}
	};

 MSBuild("./src/Sloader.Config/Sloader.Config.csproj", new MSBuildSettings().SetConfiguration("Release"));
 NuGetPack("./src/Sloader.Config/Sloader.Config.csproj", nuGetPackSettings);
 MSBuild("./src/Sloader.Result/Sloader.Result.csproj", new MSBuildSettings().SetConfiguration("Release"));
 NuGetPack("./src/Sloader.Result/Sloader.Result.csproj", nuGetPackSettings);
 MSBuild("./src/Sloader.Engine/Sloader.Engine.csproj", new MSBuildSettings().SetConfiguration("Release"));
 NuGetPack("./src/Sloader.Engine/Sloader.Engine.csproj", nuGetPackSettings);
});

Easy, right? The most interesting part here is the NuGetPack command. Before we invoke this command we need to make sure that we build the last recent version - to enforce that we just rebuild each project in release mode.

Result

The console output should make the flow pretty clear:
