Currently i am configuring the plugin in a project with mutli-module.
When i am configuring the plugin i am required to setup a global project key but i override them per module.
Why is this required since i override them per module?
I am not able to apply the configuration with an empty project key.
Is this a bug since in every module i configure, the plugin says it is bound to the authentication-service project.

Thanks in advance.
