Task error handling

[fortmarek]

Describe the bug

The task closure is marked as throwing, but errors thrown from here are not handled. I initially created a custom error and threw it as a form of validation (e.g. an invalid path provided)

To Reproduce

Create a task, throw an error inside and then run it

Expected behavior
We should handle this gracefully

@fortmarek thanks for creating these issues, I've taken a very quick look at handling error throwing but have some concerns about my implementation. You can see the code here but the things I wasn't sure about:

• This uses print to output the error because ProjectAutomation doesn't import TuistSupport so I couldn't use a logger instance
• Should error handling happen within Task.swift or should it be exiting with a message which is captured by an error handler within the ExecCommand code?

Happy to have a chat about this change, either here or I'm in the tuist slack as well

Indeed, you can't!

Should error handling happen within Task.swift or should it be exiting with a message which is captured by an error handler within the ExecCommand code?

This way we can reuse the logger functionality, so I think this is a good step forward 👍
