Description
Composer 2.2 throws an exception when updating:
[RuntimeException] Cannot set the alias loader, as it is already registered!

When reverting to composer 2.1, the error vanishes.
I'm planning on creating an comment in the official discussion about this as well, but IMHO this is an issue with TYPO3 and not composer itself.
I was able to ensure that this issue was not due to additional packages like "helhum/typo3-console" or others.
Way to reproduce (as of 25.11.2021):- Install composer snapshot (
composer self-update --snapshot) - Update packages (
composer update)

I can not reproduce that. Please post the composer.json with which you are able to reproduce this exception.

I've been able to pinpoint the reason. As it appears (and this was to be expected), this comes from a post-update-script that was needed in older versions and that was never removed:
Excerpt:
...
"scripts": {
"post-update-cmd": [
"bash scripts/include-fpm.sh"
],
...
include-fpm.sh
#!/usr/bin/env bash
match='<?php'
file='vendor/typo3/autoload-include.php'
if grep -r "REDIRECT_TYPO3_PATH_ROOT" $file
then
echo "already ok"
exit
else
echo "<?php" > $file.new
cat scripts/add.txt >> $file.new
cat $file | tail -n +2 >> $file.new
rm $file && mv $file.new $file
fi
This lead to the autoloader registering the class alias mapper twice, which did not seem to be an issue before 2.2 but now apparently is.
Ticket can be closed.

Let's see if the proposed fix in Composer is accepted. https://github.com/composer/composer/pull/10312
Otherwise the class alias loader package needs to adapt
