What are you seeing?

A NullReferenceException in the code sample below. However, that’s more the symptom than the cause. The problem appears to be that Cake Frosting is combining Directory("..") + Directory("temp") into "..temp" rather than "../temp" when you capture the context and then use expression bodied properties.

This may seem obscure, but I’m converting a large codebase of DSL Cake into Frosting and am looking for ways to accomplish it with minimal changes.

What is expected?

It should run to completion without an exception

Steps to Reproduce

Run this:

[TaskName("Fail")]
public class FailTask : FrostingTask<BuildContext>
{
    private BuildContext? _context;
    private DirectoryPath RootDir => _context.Directory("..");
    private DirectoryPath TestDir => RootDir + _context.Directory("temp");

    public override void Run(BuildContext context)
    {
        _context = context;
        context.GetFiles(TestDir + context.File("*.zip"));
    }
}

Output log

Error: System.NullReferenceException: Object reference not set to an instance of an object.
