Unable to install older Shopware versions which include hirak/prestissimo

[dblaichinger]

PHP Version

7.2

Shopware Version

6.2.3

Expected behaviour

./psh.phar docker:start runs successfully.

Actual behaviour

Error on ./psh.phar docker:start

#18 268.4 [InvalidArgumentException]
#18 268.4 Package hirak/prestissimo has requirements incompatible with your PHP version, PHP extensions and Composer version:
#18 268.4 - hirak/prestissimo 0.3.10 requires composer-plugin-api ^1.0.0 which does not match your installed version 2.2.0.

How to reproduce

Re-production steps

1. git checkout v6.2.3
2. ./psh.phar docker:start

Cause

• php-apache image uses Composer v2 by default, which makes the require of hirak/prestissimo unnecessary.

Solutions

• Either remove package from https://github.com/shopware/development/blob/v6.2.3/dev-ops/docker/containers/app/Dockerfile#L39

• Or set Composer v1 explicitly:

RUN composer1 install -d /app
ENV COMPOSER_VERSION=1
