Using --ignore-parse-errors works but keep the lot of warning messages.

It would be great to see which files causes this error.

Can you try running with -vvv?

[soullivaneuh]

Of course, but you have nothing more:

$ ./docker-console composer-require-checker -vvv

Regarding the warnings:
This seems to be related to a * within an exclude-from-classmap key, that makes the regex invalid, but I currently do not understand why this fails, because I think we're using the same logic like the composer classmap generator.
Could you please check if composer dump-autoload -o gives these warnings, too?

The Syntax error could also be caused by a short open tag, you could try running the phar file with:

php -d short_open_tag=1 composer-require-checker.phar

and see if this fixes the problem.

If this does not help, could you please add your composer.lock file, so I could see if I find any hints what could cause the problems?

[soullivaneuh]

Here is the result of the dump-autoload:

$ composer dump-autoload -o

Concerning the short_open_tag:
