Generating optimized autoload files error → Could not scan for classes inside

[remcotolsma]

After running composer install --no-dev --prefer-dist --optimize-autoloader we noticed the following error:

Generating optimized autoload files

  In ClassMapGenerator.php line 73:

    Could not scan for classes inside "vendor/mck89/peast/test/Peast" which does not appear to be a file nor a folder

Is this related to the following:

peast/composer.json

Lines 18 to 23 in bd4c30d

	"autoload": {
	"psr-4": {
	"Peast\\": "lib/Peast/",
	"Peast\\test\\": "test/Peast/"
	}
	},

peast/.gitattributes

Line 5 in bd4c30d

/test export-ignore

The test folder is part of export-ignore but is registered in the composer.json autoload property.

Should it be moved the autoload-dev property?

    "autoload": {
        "psr-4": {
            "Peast\\": "lib/Peast/"
        }
    },
    "autoload-dev": {
        "psr-4": {
            "Peast\\test\\": "test/Peast/"
        }
    },

Yes, I think you're right, i'll make some tests to check different cases with the fix you proposed.

I've applied the fix you proposed and it seems to work. I couldn't reproduce the error you mentioned but i think it depends on the composer version, so let me know if the error is still present. Thank you!
