This is ready for review, I'd love it if someone could confirm this doesn't break builds for them!

I've confirmed that this doesn't affect building on Linux on account of the CI still working:

https://github.com/doinkythederp/CKAN/actions/runs/13471224444

Ubuntu 24.04 says:

media/sf_CKAN/build/BuildContext.cs(128,14): error CS0121: The call is ambiguous between the following methods or properties: 'string.Split(char[]?, StringSplitOptions)' and 'string.Split(string?, StringSplitOptions)' [/media/sf_CKAN/build/Build.csproj]

Possibly a dotnet versioning thing? This VM has 8.0.112.

Resolved in 9cf2633 (#4320)

OK, I can now build on all systems, so I'm reviewing the actual changes.

Looks like the target defaulting is broken:

> .\build.ps1 test

Error: Unknown command 'test'.

       test
       ^^^^ No such command

$ ./build.sh test

Error: Unknown command 'test'.

      test
      ^^^^ No such command

That's one of the things that was deleted in build and build.ps1, looks like it wasn't carried forward to the new stuff?

CKAN/build.ps1

Lines 46 to 52 in 27c6d9a

	if ($Arg0) {
	if ($Arg0[0] -eq "-") {
	$cakeArgs += "${Arg0}"
	} else {
	$cakeArgs += "--target=${Arg0}"
	}
	}

CKAN/build

Lines 48 to 57 in 27c6d9a

	if [ -n "$arg0" ]; then
	case $arg0 in
	-*)
	cakeArgs="$cakeArgs $arg0"
	;;
	*)
	cakeArgs="$cakeArgs --target=$arg0"
	;;
	esac
	fi

Oops! I think when I applied the template for Cake Frosting it must have overwritten that.
