Setup:di:compile verbosity does nothing

[adamlavery]

Summary (*)

setup:di:compile produces no useful output when there is a coding error. Using -v, -vv, -vvv or --verbose does nothing to help. The stack trace doesn't identify the file being processed let alone the source line of the error. If we've uploaded multiple files, none of which show any error in the code editor, we have no indicators where to find the code error.

Examples (*)

$ bin/magento set:di:com -vvv
Compilation was started.

Nothing here indicates where the error is.

Proposed solution

As a minimum, the ClassLoader must identify the class it is trying to load. Preferably it would also include the line that generated the error.

✔️ Issue Confirmed

Tried to reproduce the issue on magento 2.4-develop and its reproducible.

Manual testing scenario:

1. Clean Magento setup
2. Created coding error by adding some extra or wrong operator in controller
3. Executed bin/magento set:di:com -vvv
4. Also tried with -v, -vv options
5. We are getting the error on compile

Expected Result:
We should get the proper indication that where the error is or where to find the error. Verbosity is not working, on error it should tell the file or specifically line that generated the error

Actual Result:
Getting the error without any clear indication of class or file.

As per above findings confirming the issue.
