Composer version 2.0 errors

[meanderix]

I'm seeing the following error when building this image in my current Openshift-project:
You are using Composer 2, which some of your plugins seem to be incompatible with. Make sure you update your plugins or report a plugin-issue to ask them to support Composer 2.

It looks like this image does not have an option to install a specific composer version?

It should be possible to specify a version when running the setup-script, like this:
php composer-setup.php --version=1.10.16

I opened this PR for this exact reason :) #313

Hello,

I did try the s2i builder from master branch with this php project https://github.com/tobru/drupal-openshift.git#openshift, my aim is to build drupal application and deploy it to OpenShift.

I don't know if the master branch was updated, but I am still facing this issue:

    - wikimedia/composer-merge-plugin is locked to version v1.3.0 and an update of this package was not requested.
    - wikimedia/composer-merge-plugin v1.3.0 requires composer-plugin-api ^1.0 -> found composer-plugin-api[2.0.0] but it does not match the constraint.

In my local I commented the following line of the assemble script:
./composer.phar install --no-interaction --no-ansi --optimize-autoloader $COMPOSER_ARGS

What implications has commenting this line?

It's normal that this error happens to me too right?

Kind regards,

#313 has not been merged into master yet. That repo https://github.com/tobru/drupal-openshift#openshift is really old, I would find a newer guide on how to run Drupal on OpenShift / Kubernetes If I were you.
