Debugging causes "More than one build script specified" error if a space exists in the file path

[cmbaldock]

If I try to debug a cake file in Visual Studio Code that contains a space in the directory name then I always get a "More than one build script specified" error. This doesn't occur if there are no spaces in the directory name.

I'm using the standard launch.json file specified below:

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [
    
        {
            "name": "Cake: Debug Script (CoreCLR)",
            "type": "coreclr",
            "request": "launch",
            "program": "${workspaceRoot}/tools/Cake.CoreCLR/Cake.dll",
            "args": [
                "${workspaceRoot}/build.cake",
                "--debug",
                "--verbosity=diagnostic"
            ],
            "cwd": "${workspaceRoot}",
            "stopAtEntry": true,
            "externalConsole": false
        }
    ]
}

The output when I debug a build.cake file in the directory "D:\Temp\Cake Test" is as follows:

What happens if you quoted your document? I.e.

"\"${workspaceRoot}/build.cake\""

[cmbaldock]

I did give that a go. Unfortunately the same error occurred.

I have the same issue

This is an issue with VSCode's launch behavior. I investigated this months ago. You could fix this in Cake, but the underlying issue is that VSCode escapes quotes from strings in the launch.json before passing it to the executable.

Where exactly this is happening inside vscode i don't know (i am having a really hard time getting behind typescript project structure), but i debugged into omnisharp to know its happening in vscode not in omnisharp.
