When running composer update phpro/grumphp to update from 0.11.1 to 0.11.2 the follow error is thrown after (or during) the autoload files are generated:

[Symfony\Component\Debug\Exception\FatalThrowableError]
  Class 'GrumPHP\Console\Command\ConfigureCommand' not found

This is likely due to the change from PSR-0 to PSR-4 in 0.11.2 (or rather the change of folder structure since PSR-4 allows the PSR-0 structure) since the autoloader used by the Composer plugin have the old paths and thus can't find the file/class when the folder structure changes.

Not sure there's a fix for this really, or if it's worth fixing - but figured I'd report it at least :)

Steps to reproduce:

mkdir tmp
cd tmp
composer require phpro/grumphp 0.11.1
composer require phpro/grumphp 0.11.2 -vvv

Result:

$ composer require phpro/grumphp 0.11.2 -vvv

Indeed, that looks related to the PSR4.
It can be fixed by replacing the COMMAND_NAME constants with its values in the GrumPHPPlugin, but that is something I would like to avoid.
The error only occurs once. After that it keeps on working.

Until it is fixed, you might want to remove the old version before installing the new one:

composer remove phpro/grumphp
composer require phpro/grumphp 0.11.2

@jyggen: I've tried fixing the errors by hardcoding the strings, but then the installation fails on other positions. I'll add the remark to the release notes and close this issue for now. It just isn't worth fixing :)
