Comment for myself (and others too)

MolliePlugin install is fine with Sylius Standard Edition but not with Developer Edition.

From what you show. You are trying to install a plugin on a Sylius repo. You do not use the tag, only one of the branches (master? I think). That's why composer determined it was 1.0.0. Mollie plugin requires minimum version 1.1. You must switch branch to tag above 1.1 or use branch alias https://getcomposer.org/doc/articles/aliases.md
